Dr Biswarup Paul (Universita e INFN Torino (IT))22/01/2018, 17:00Relativistic Heavy Ion PhysicsPosterThe ALICE Collaboration has studied inclusive J/$\psi$ and $\psi$(2S) production in p-Pb collisions at $\sqrt{s_{\rm NN}}$ = 5.02 and 8.16 TeV. The measurements were performed at forward (2.03 $<$ $y_{\rm cms}$ $<$ 3.53), mid ($-$1.37 $<$ $y_{\rm cms}<$ 0.43) and backward ($-$4.46 $<$ $y_{\rm cms}$ $<$ $-$2.96) centre of mass rapidities. In this presentation, the nuclear modification factor of...Go to contribution page

Mr Stefan Lunkenheimer (KPH)22/01/2018, 17:03Nuclear Structure and AstrophysicsPosterMAGIX is a versatile fixed-target experiment and will be built on the new accelerator MESA (Mainz Energy-Recovering Superconducting Accelerator) in Mainz. The accelerator will deliver polarized electron beams with currents up to $1\,\mathrm{mA}$ and energy up to $105\,\mathrm{MeV}$. Using its internal gas-target, MAGIX will reach a luminosity of...Go to contribution page

Efrain Segarra (Massachusetts Institute of Technology)22/01/2018, 17:06Hadron PhysicsPosterThe EMC effect, the phenomenon by which quark distributions are modified in bound nucleons, has defied explanation since its discovery over 30 years ago. Recently, there have been indications, experimentally and theoretically, that the EMC effect may be linked to high-momentum nucleons. Rather than the EMC effect being caused by a modest modification in all nucleons, it is possible that highly...Go to contribution page

Mr Klemens Lautenbach (JLU Giessen)22/01/2018, 17:09Applications and InstrumentationsPosterThe future Belle II experiment will reach a total luminosity of $8\cdot 10^{35} cm^{−2} s^{−1}$. With such high luminosities, the innermost detector, the Pixeldetector (PXD), will produce raw data rates of up to 20 GB/s. In order to reduce these rates, a high bandwidth data aquisition and data reduction system for the PXD is required. The so-called ONline SElection Node (ONSEN)-system will...Go to contribution page

Pascal Dillenseger (for the ALICE Collaboration)22/01/2018, 17:12Relativistic Heavy Ion PhysicsPosterJ/$\psi$ measurements in Pb$-$Pb collisions at $\sqrt{s_{\rm NN}}$ = 2.76 TeV clearly show a smaller suppression than the one expected from color screening, when compared to binary-scaled pp collisions. The increased yield in Pb$-$Pb collisions can be explained by models that contain a (re)generation component, based on the (re)combination of c$\overline{\rm{c}}$-quarks. Hence, one of the...Go to contribution page

Mr Viacheslav Tsaran (JGU Mainz)22/01/2018, 17:15Nuclear Structure and AstrophysicsPosterThe method of coherent $\pi^0$ photoproduction ( $\gamma$+ A${}_\text{g.s.}$ $\rightarrow$ $\pi^0$+ A${}_\text{g.s.}$, where A${}_\text{g.s.}$ is a nucleus in its ground state) provides an efficient tool to study nucleon distribution and the neutron skin of various nuclei. We investigate the case of nuclei with zero spin and isospin from the theoretical point of view in the framework of a...Go to contribution page

Mr Dimitar Mihaylov (TU Munich)22/01/2018, 17:18Hadron PhysicsPosterFemtoscopy is a method used to investigate particle correlations by using the experimentally accessible two-particle momentum correlation function C(k). This function can be mathematically obtained by integrating the product of the source function and the two-particle wave function. The main goals of femtoscopy are to investigate the properties of the emission source and the interaction...Go to contribution page

Dr Savvas Zafeiropoulos (Universitaet Heidelberg)22/01/2018, 17:21PosterIoffe-time distributions, which are functions of the Ioffe-time $\nu$, are the Fourier transforms of parton distribution functions with respect to the momentum fraction variable $x$. These distributions can be obtained from appropriate equal time, quark bilinear hadronic matrix elements which can be calculated from first principles via lattice QCD methods. Here, we present the first...Go to contribution page

Mr Moritz Greif (Goethe University Frankfurt)22/01/2018, 17:24Relativistic Heavy Ion PhysicsPosterWe calculate all diffusion constants of the conserved baryon, electric and strangeness charge in hot relativistic multi-component systems using kinetic theory. Applying the algorithm for massive pions, kaons, nucleons, lambda- and sigma-baryons, with resonance cross sections when possible, we present for the first time realistic values for the hadronic diffusion coefficient matrix. These...Go to contribution page

Mr Lumkile Msebi (University of Johannesburg)22/01/2018, 17:27Nuclear Structure and AstrophysicsPosterCharacteristic decay properties of radionuclides are essential in the study of nuclear spectroscopy. Lifetime measurements and transition moments for excited nuclear levels form part of this extensive study that seeks to unveil properties of nuclear structure. Scintillation detectors prove to be formidable in gamma ray detection and lifetime measurements. With advent of LaBr3...Go to contribution page

Yvonne Stöttinger (Universität Mainz)22/01/2018, 17:30Nuclear Structure and AstrophysicsPosterThe electromagnetic form factors of light nuclei provide a sensitive test of our understanding of nuclei. The deuteron in particular, as the only bound two-nucleon system, is a fundamental system that has received extensive attention in the past, by both theory and experiment. Because the deuteron has spin one, three form factors are needed to fully describe the electromagnetic structure of...Go to contribution page

Ms Julia Sammet (Goethe University Frankfurt)22/01/2018, 17:33Hadron PhysicsPosterWe calculate two- and three-body decays of the (lightest) vector glueball into (pseudo)scalar, (axial-)vector, as well as pseudovector and excited vector mesons in the framework of an effective model of QCD. While absolute values of widths cannot be predicted because the corresponding coupling constants are unknown, some interesting branching ratios can be evaluated by setting the mass of...Go to contribution page

Mr Leonard Koch (JLU Giessen)22/01/2018, 17:36Applications and InstrumentationsPosterThe BESIII experiment at the BEPCII electron positron collider at IHEP (Beijing) is collecting data in the charm-$\tau$ mass region. In electron positron collisions one of the initial leptons may emit a real photon before the annihilation (initial state radiation, ISR). As a result, the remaining system is boosted and has an effective center-of-mass energy lower than the nominal one...Go to contribution page

Stephan Aulenbacher (JGU Mainz)22/01/2018, 17:39Applications and InstrumentationsPosterIn the Year 2017 a new target has been installed @A1 in Mainz. This target is a Cluster-Jet-Target, which means that a hydrogen jet streams through the vacuum chamber, perpendicular to Mamis electron beam. By cooling down to gas temperatures of 40 K, the gas jet gets high densities in the core, due to the formation of clusters. The Jet-Target enables high precision measurements due to its...Go to contribution page

Dr Dagmar Adamova (Nuclear Physics Institute AS CR)22/01/2018, 17:42Applications and InstrumentationsPosterAfter the LHC community successfully completed Run 1, the capacity of the Worldwide LHC Computing Grid (WLCG) became the limiting factor in the processing of ever growing volumes of data produced from LHC collisions. During the last five years the LHC community launched a number of activities to increase computing performance and optimize usage of available resources.

Dr Savvas Zafeiropoulos (Universitaet Heidelberg)22/01/2018, 17:45PosterWe study the Stephanov model, which is a Random Matrix Theory model for QCD at finite baryon density, using the Complex Langevin algorithm. Naive implementation of the algorithm shows convergence towards the phase quenched or quenched theory rather than to the intended theory with dynamical quarks. A detailed analysis of this issue various potential resolutions of the failure of this...Go to contribution page

Dr Bo Mei (Extreme Light Infrastructure - Nuclear Physics (ELI-NP))22/01/2018, 17:51Nuclear Structure and AstrophysicsPosterThe investigation of very neutron-rich nuclei are of significant importance for nuclear physics and nuclear astrophysics. However, so far, only few neutron-rich nuclei near the stability have been measured, while most neutron-rich nuclei have not been experimentally studied due to their small production cross sections and short half-lives. Very brilliant and intense gamma beams planned at...Go to contribution page
