Description
The XIIth International Conference on Heavy Quarks and Leptons is dedicated to the study of the heavy quarks charm, bottom, and top with obvious extensions to interesting topics involving the strange quark. Neutrino oscillation studies and new insights in mu and tau lepton phenomenology are also included. The conference continues the tradition of regular scientific meetings, first started in 1993 at the Laboratori Nazionali di Frascati under the name "Heavy Quarks at Fixed Target", and widened in 2002 to include leptons with the workshop renamed to what is known as today.

        Heavy Quarkonium Spectroscopy and Beyond 40m
        After a dozen of very lively years, the spectra of heavy quarkonia below thresholds are almost complete; the last system to be explored is the Bc meson. Since few years, most discoveries happened close to open flavor thesholds, and four quark systems have attracted interest as the new spectroscopy frontier. This review will cover the unresolved questions on conventional quarkonia, the links between these spectra and the ones of heavy-light mesons and baryons, and the state-of-the-art of the so called XYZ zoo .

        "Search for exotic charmonium" on behalf of BaBar and Belle. 30m
        One of the most intriguing puzzles in hadron spectroscopy are the numerous charmonium-like states observed in the last decade, including charged states that are manifestly exotic. Over the years BaBar has extensively studied these states in B meson decays, initial state radiation processes and two photon reactions. We report new and additional studies on some of these states performed using the entire data sample collected by BaBar in e+e- collisions at center of mass energies near 10.58 GeV/c^2. Among these, the study of the process B -> J/psi phi K with a search for the X(4140) and X(4270) in their decays to J/psi phi, and a search for charged charmonium-like state Zc(3900)^+ in the decay Y(4260) -> J/psi pi+pi-.

        We perform an analysis of the D+ -> Ks pi+ pi0 Dalitz plot. The Dalitz plot is found to be well-represented by a combination of six quasi-two-body decay channels (Ks rho, Ks rho(1450), K*0bar pi+, K*0(1430)bar pi+, K(1680)bar pi+ and kapa0bar pi+) plus a small non-resonant component. Using the fractions from this analysis, partial branching ratios are updated with higher precision than previous measurements.

        New ways to search for right-handed current in B -> ρ l ν 30m
        An interesting possibility to ease the tension between various determinations of |Vub| allows a small right-handed contribution to the Standard Model weak current. The current bounds on such a contribution are fairly weak. We propose new ways to search for such a beyond Standard Model contribution in the semileptonic B -> ρ l ν decay. We suggest to use generalized asymmetries in one, two, or three angular variables as discriminators, which do not require measuring the fully differential distribution, and discuss its theoretical uncertainties. We discuss how binned measurements can access all the angular information, which may be more important for B -> ρ l ν than it is for B -> K* l+ l-. We explore the achievable sensitivity both from the available BaBar and Belle data sets, as well as from the anticipated 50 ab^-1 Belle II data.

        Recent results on semileptonic B and Bs decays from Belle 25m
        Semileptonic B meson decays, B ➞ X l ν, are currently the preferred modes for determining the Cabibbo-Kobayashi-Maskawa (CKM) matrix elements |Vcb| and |Vub|, two fundamental parameters of the Standard Model. At the same time they can also be used to test and refine the theoretical tools used for describing B mesons and their decays. Based on the large data sample accumulated by the Belle experiment at the KEKB asymmetric energy e+ e- collider at KEK, Japan, we present new results on semileptonic B and Bs meson decays.

        Based on the psi(3770) -> DDbar data accumulated at the BESIII experiment, we present studies of D0 -> K- e+ nu and D0 -> pi0 e+ nu decays which include preliminary results of B(D0 -> K- e+ nu) , B(D0 -> pi- e+ nu), as well as the partial decay rates of these decays in q^2 bins. The measured partial decay rates, in return, allow us to determine different parameterizations of the form factors. We also report a measurement of B(D+ -> mu+ nu_mu) which allows us to extract a product of the D+ decay constant and a CKM matrix element, f_D+ * |Vcd|.

        Charmless b-hadron decays are suppressed in the Standard Model by tiny CKM matrix elements which brings the tree amplitudes to levels comparable with loop amplitudes, and potentially New Physics amplitudes. CP violation measurements using Dalitz plot analyses in multi-body decays allow to disentangle these various contributions. We report about the most recent measurements of large CP violation effects and observations of new decay modes.

        News on the double beta decay search 25m
        While neutrino oscillation experiments have finally provided the incontrovertible evidence that neutrinos mix and have finite masses the absolute scale and ordering of the masses of the three generations as well as charge conjugation and lepton number conservation properties are still unknown. In this scenario, a unique role is played by the Neutrinoless Double Beta Decay searches: these experiments can probe lepton number conservation, investigate the Dirac/Majorana nature of the neutrinos and their absolute mass scale (hierarchy problem) with unprecedented sensitivity. Today Neutrinoless Double Beta Decay faces a new era where large scale experiments with a sensitivity approaching the so-called degenerate-hierarchy region are nearly ready to start and where the challenge for the next future is the construction of detectors characterized by a tonne-scale size and an incredibly low background, to fully probe the inverted-hierarchy region. Recent results and future projects are discussed.

        Status of direct neutrino mass measurements 25m
        Experimental information about the neutrino masses and lepton mixing is important both for cosmology and particle physics. Cosmological observations and neutrinoless double beta decay experiments provide an indirect access to the absolute neutrino mass scale, but are model-dependent. A model independent, direct way to measure the neutrino masses is the investigation of the kinematics of single beta decay via a precise measurement of the beta decay electron energy spectrum close to the endpoint. The talk will give an overview of direct experimental methods for neutrino mass measurements and present the status of different experiments. In case of the KArlsruhe TRItium Neutrino (KATRIN) experiment the experimental setup and status of the experiment will be described in more detail. The KATRIN experiment is designed to determine the absolute neutrino mass scale, with a sensitivity of 200 meV, by a precise energy measurement of decay electrons from tritium beta-decay close to the endpoint of the energy spectrum.

        An update on solar neutrino physics 25m
        The Sun as a well-defined neutrino source provides extremely important opportunities to investigate nontrivial neutrino properties such as nonzero mass, flavor mixing, neutrino oscillations, and MSW effect. The solar neutrino flux is energetically broadband, free of flavor backgrounds, and passes through quantities of matter obviously unavailable to terrestrial experiments. In this talk, after an introduction to solar neutrino phenomenology, I will describe the key features of solar neutrino experiments and I will summarize results and implicatiosn about solar neutrino detection and oscillations.

        Accelerator Neutrino Experiments 25m
        Accelerator neutrino experiments using intense beams of muon neutrinos provide a well-controlled window into the new physics of the PMNS sector which expands the conventional standard model. Long-baseline experiments are providing significantly improved precision on oscillation phenomena using matter effects, appearance and disappearance channels, and neutrinos and antineutrinos. Other experiments at shorter baselines have very large data samples, enabling greatly improved measurements.This talk will present results from a suite of accelerator experiments which address the physics of the three-neutrino model, possible non-standard interactions, and neutrino cross-sections.

        Reactor Neutrino Experiments (Double Chooz, RENO) 25m
        The θ13 parameter of the PMNS mixing matrix remained unknown until the first hints and estimates by both reactor and beam experiments in 2011. The most competitive limit set by the Chooz experiment let indeed open the hypothesis of a null value. A precise measurement of a non zero value enables a future observation of the CP violation and the estimate of its phase δ. The Double Chooz experiment was designed in this context and aims for a precision measurement of the θ13 neutrino mixing angle. Located at the Chooz nuclear power plant in north-eastern France, it is searching for disappearance of antineutrinos produced by the two reactors. Double Chooz relies on a two identical detector measurement. The near detector, located at a few hundred meters from the cores, before the impact of θ13 is exerted, aims at monitoring the νe flux emitted by the reactors. The far detector is located at a distance of about one kilometer from the reactor cores, near the expected first maximum amplitude of the oscillation. The comparison of these two measurements gives an estimate of the deficit induced by the oscillation, canceling most of systematic uncertainties related to neutrino flux emission and detection. The far detector began data taking in April 2011 and gave the first hint of a non zero value of θ13 by a reactor experiment that same year. The analysis enhancements and the latest results of the experiment, based on a far detector only measurement, will be presented. Data taking in the near detector is about to start, enabling a significant reduction of both reactor and detector related systematic uncertainties in a near future. The RENO experiment, located near the six Yonggwang reactors in South Korea, is based on the same two detector concept as Double Chooz. The data taking began in summer 2011 and the first θ13 results were published in 2012. The latest results released by the RENO collaboration will also be presented in this talk.

        Precision Results on θ_13 from Daya Bay 20m
        The Daya Bay Reactor Neutrino Experiment measures the neutrino mixing angle θ_13 with high sensitivity, using functionally identical detectors at appropriate distances from the cores of a nuclear power plant. We have analyzed 217 days of data with six detectors, and 404 days with the full complement of eight detectors, obtaining a sample of over two million ν ̄ep → e+n events. Combining rate and spectral shape information, we find sin^2 2θ_13 = 0.084 ± 0.005 and ∆m^2 = (2.44+0.10-0.11) × 10^−3 eV^2 for events where the neutron captures on gadolinium. Also, using the six detector data set and a rate analysis based on np capture, we find sin^2 2θ_13 = 0.083 ± 0.018. We will present details of these results, including a discussion of backgrounds and systematic uncertainties.

        Experimental searches on sterile neutrinos 25m
        While neutrino oscillations among the three active neutrino flavors are by now well established, several anomalies observed at relatively short baselines in oscillation experiments hint towards the existence of one or more additional sterile neutrino flavors. As a consequence, several experiments are in preparation that are dedicated to test the sterile neutrino hypothesis. The present contribution gives an overview of the on-going experimental efforts, highlighting the two projects that are foreseen to start in 2015: SOX deploying a radioactive neutrino source at short distance from the BOREXINO detector at LNGS, and STEREO searching for sterile neutrino oscillations at short distance from the ILL reactor core.

        ChPT tests at NA48 and NA62 experiments at CERN 25m
        New final results from an analysis of about 400 K+- --> pi+- gamma gamma rare decay candidates collected by the NA48/2 and NA62 experiments at CERN during low intensity runs with minimum bias trigger configurations are presented. The results include a model-independent decay rate measurement and fits to Chiral Perturbation Theory (ChPT) description. The data support the ChPT prediction for a cusp in the di-photon invariant mass spectrum at the two pion threshold. The NA48/2 Collaboration at CERN has accumulated unprecedented statistics of rare kaon decays in the Ke4 modes Ke4(+-) to pi+ pi- e nu and Ke4(00) to pi0 pi0 e nu with ~one percent background contamination. The detailed study of form factors is sensitive to small isospin symmetry breaking effects. This brings new inputs to low energy QCD description and crucial tests of predictions from Chiral Perturbation Theory and lattice QCD calculations.

        Recent KLOE results on Kaon Physics 25m
        The KLOE experiment at the DAΦNE φ-factory of the INFN Frascati Laboratory collected data corresponding to 2.5 fb^−1 of integrated luminosity. Neutral kaon pairs produced in φ-meson decays offer unique possibilities to perform tests of fundamental discrete symmetries. The entanglement of the two kaons is exploited to search for possible violation of CPT symmetry and Lorentz invariance in the context of the Standard-Model Extension (SME) framework. A new approach to the analysis of φ -> K_S K_L -> π+ π-, π+ π- events has been adopted allowing us to independently measure all four CPT violating parameters Δ a_μ appearing for neutral kaons in the SME. The final KLOE results on Δ a_μ will be presented. These are presently the most precise measurements in the quark sector of the SME. We also shortly discuss the perspectives for a new measurement using the KLOE-2 apparatus equipped with a new inner tracker. The measurement of the absolute BR of of the K+ -> 3π(γ) decay completes the KLOE program of precise and fully inclusive kaon dominant BR's measurements. The most recent result, BR(K± -> π± π+ π-) = (5.56 ± 0.20) % (Chiang et al.), dates back to more than 30 years ago. We use as normalization sample the tags given by K -> μν and K -> ππ0 decays. The track of the tagging kaon is backward extrapolated to the interaction point, then the kinematics of the decay φ -> K+ K-, gives us the possibility to define the path of the signal kaon (direction and momentum). The decay products of the kaons have a very low momentum, less than 200 MeV/c, and curl up in the KLOE magnetic field (0.52 T). To optimize the quality of the track reconstruction we select kaons decaying before the Drift Chamber Inner Wall (inner radius(DC) = 25 cm), so that only their decay products cross the DC (three tracks instead of four). We require at least two reconstructed tracks (pion candidates) and we count the number of K -> 3π(γ) decays from the missing mass spectrum. The final KLOE result on the BR(K+ -> π+ π- π+ (γ)) will be presented.

        Recent results and prospects of rare kaon decay measurements at LHCb 25m
        Kaon decays are a new area of interest at the LHCb experiment. A search for the decay K0S -> mu+ mu- is performed, based on a data sample of 1.0 fb^-1 of pp collisions at sqrt(s) = 7 TeV. The observed number of candidates is consistent with the background-only hypothesis, yielding an upper limit of B(K0S -> mu+ mu-) < 11 (9) x 10^-9 at 95 (90)% confidence level. This limit is a factor of thirty below the previous measurement. Prospects for this and other decays of strange particles are also presented.

The experimental setup is based on the upgraded detector of KEK experiment E246 and includes a large-acceptance toroidal spectrometer for tracking charged particles with high resolution, combined with a photon calorimeter with large solid angle.

        Recent results and prospects for precision tests of the Standard Model in kaon decay in flight experiments at CERN are presented. A measurement of the ratio of leptonic decay rates of the charged Kaon at a 0.4% precision constrains the parameter space of new physics models with, for example, an extended Higgs sector. Searches for neutrino mass states and the dark photon in the ~100 MeV/c^2 mass range based on samples collected in 2003-2007 are in progress and prospects will be discussed. The NA62 experiment starting in 2014 will search for a range of lepton number and lepton flavour violating decays of the charged kaon and the neutral pion at improved sensitivities down to ~10^{-12}, probing new physics scenarios involving, for example, heavy Majorana neutrinos. The foreseen NA62 L0 trigger strategy for rare decays will be discussed.

        Recent results on top quark properties and interactions are presented, obtained using data collected with the CMS experiment during the years 2011 and 2012 at 7 TeV and 8 TeV center-of-mass energy. Measurements are performed for the inclusive and differential top quark pair production cross sections in several top quark final states. The mass of the top quark is extracted using several methods, including indirect constraints from the measured cross section. Cross sections for the electroweak production of single top quarks in both t- and tW-channels are also measured, and limits are set on s-channel production. Further results include measurements of top quark properties, such as the W helicity in top decays, the top pair charge asymmetry, the top quark charge as well as the search for anomalous couplings in both pair and single top-quark production. The results are compared with predictions from the standard model.

        Summary of recent top results from D0 30m
        I present an overview of recent measurements by the D0 experiment in the top quark sector: the forward-backward asymmetry A_FB in tt production due to higher order effects of QCD, both inclusive and differential as a function of the mass of the ttbar pair, the differential tt production cross sections, the evidence for single top quark production in the s-channel, and, to conclude, the world's most precise single measurement of the mass of the top quark. The measurements are performed employing the full set of data corresponding to 9.7 fb-1 acquired by the D0 experiment in Run II of the Fermilab Tevatron proton-antiproton collider at a centre-of-mass energy of sqrt(s)=1.96 TeV.

        LHCb Upgrade 30m
        The LHCb experiment is designed to perform high-precision measurements of CP violation and search for New Physics using the enormous flux of beauty and charmed hadrons produced at the LHC. The operation and the results obtained from the data collected do far demonstrate that the detector is robust and functioning very well. We therefore plan for an upgraded spectrometer by 2018 with a 40 MHz readout and a much more flexible software-based triggering system that will increase the data rate as well as the efficiency specially in the hadronic channels. Here we present the LHCb detector upgrade plans, based on the recently published technical design reports.

        Status and Prospects of the NOvA Experiment 30m
        The NOvA experiment, now nearing completion, is a new long-baseline neutrino experiment that will use an upgraded NuMI neutrino source at Fermilab and a 14-kton detector at Ash River, Minnesota. NOvA uses a highly active, finely segmented detector design that offers superb event identification capability, allowing precision measurements of electron (anti-)neutrino appearance and muon (anti-)neutrino disappearance. Through these, NOvA will provide new measurements of theta_13, theta_23, the atmospheric mass splitting, the neutrino mass hierarchy, and the CP-violating phase. This talk reviews the experiment's construction and operation timeline.

        Status and Prospects of the Belle II Experiment 30m
        The Belle II experiment is a new generation B-factory experiment at KEK in Japan. The construction of the SuperKEKB accelerator and the Belle II detector is now in progress aiming at the commissioning in 2016. In the conference, the physics motivation of the experiment, the search for New Physics in the enormous number of B meson and other decays, is discussed in detail with a view of the search strategy. The current construction status of the accelerator and detector is also reported, and the possible commissioning scenario is described.
