24. Internal Target Experiments at the MESA accelerator

Dr Harald Merkel (Institut für Kernphysik, Johannes Gutenberg-Universität Mainz)

Hadron Physics

Short Contribution

The Mainz Energy recovery Superconducting Accelerator (MESA) is currently under construction. The accelerator principle of an energy recovery linac will provide a high polarized electron beam with a beam current of up to 10mA with high polarization and an excellent beam quality at the same time, however at a modest end-point energy of around 100 MeV. The high internal current allows to use a...

28. Precision mass measurements of neutron-rich cadmium for r-process studies

Nuclear Structure and Astrophysics

Short Contribution

The rapid neutron capture process (r-process) is believed to be responsible for the creation of a big portion of the elements heavier than iron. The path of the r-process proceeds in a region of the chart of nuclides where no or little experimental information is available. While astrophysical scenarios are available, they are all require significant experimental input from nuclear...

43. Beyond the isobar model

Mr Mikhail Mikhasenko (HISKP, Uni Bonn)

Hadron Physics

Short Contribution

From new precise data of the modern experiments, it becomes clear that the pure isobar model works only qualitatively and not able to describe the data in presence of many inelastic channels. The final state interactions modify the shape of isobars and produce additional structures on the Dalitz plot as well as on the 3 particles mass distribution. The first order correction to the isobar...

5. Measurement of the ridge and bose-enstein correlations in pp and pPb collisions with the ATLAS detector at the LHC

Dr Michael Ryan Clark (CERN)

Relativistic Heavy Ion Physics

Short Contribution

ATLAS measurement of azimuthal correlations between particle pairs at large pseudorapidity separation in pp and pPb collisions are presented. The data were collected using a combination of the minimum-bias and high track-multiplicity triggers. A detailed study of the dependence of two-particle correlations on the charged particle multiplicity, transverse momentum of the pair constituents and...

36. Measurement of the beam normal single-spin asymmetry of Carbon-12

Dr Anselm Esser (Inst. f. Kernphysik / Uni Mainz)

Nuclear Structure and Astrophysics

Short Contribution

Beam-normal single-spin asymmetry in the elastic scattering of electrons is a direct probe for the two photon exchange. At the Mainz Mictrotron, this asymmetry has been measured for Carbon-12 at a Q² of 0.04 GeV². A 570 MeV continuous wave electrons beam was scattered on a carbon target and detected by two magnetic spectrometers. Quartz glass cherenkov detectors located at the elastic line in...

8. Charm Physics at BESIII

Dr Li Lei (ihep)

Hadron Physics

Short Contribution

The BESIII Experiment at the Beijing Electron Positron Collider (BEPCII) has accumulated the world's largest e+e- collision samples at psi(3770) peak, around the psi(4040) nominal mass, and at the Lambda_c-pair mass threshold which allow us to study decays of charmed mesons and baryons in a uniquely clean background. In this talk, we will review our recent results including: (1) the...
