Feasibility studies of the time-like proton electromagnetic form factor measurements with PANDA at FAIR
The possibility of measuring the proton electromagnetic form factors in the time-like region at FAIR with the PANDA detector is discussed. Detailed simulations on signal efficiency for the annihilation of p̄+ p into a lepton pair as well as for the most important background channels have been performed. It is shown that precision measurements of the differential cross section of the reaction p̄+ ...
متن کاملOverview of Nucleon Structure Studies ⋆
A brief overview of the recent activity in the measurement of the elastic electromagnetic proton and neutron form factors is presented. It is discussed how the quality of the data has been greatly improved by performing double polarization experiments, and the role of two-photon exchange processes will be highlighted. The spatial information on the quark charge distribibutions in the nucleon re...
متن کاملNew Measurements of Nucleon Structure from HERMES
Recent measurements of the spin-dependent deep inelastic scattering structure functions of the nucleon g p;n 1 (x) are presented. Theoretical diiculties with the traditional separation of the total integral ? p;n of the structure functions into contributions from quark avours is discussed. Techniques using the measurements of semi-inclusive asymmetries that allow direct separation of the avour ...
متن کاملStudies of Nucleon Spin Structure at HERMES
The HERMES experiment studies the spin structure of the nucleon using polarized semi-inclusive deep-inelastic positron scattering and polarized quasi-real photoproduction. Previous analyses of nucleon spin structure combine inclusive deepinelastic scattering data and measured hyperon decay constants assuming SU(3)flavor symmetry; asymmetries in the processes studied at HERMES may constrain nucl...
متن کاملFeasibility studies of time-like proton electromagnetic form factors at PANDA at FAIR
Simulation results for future measurements of electromagnetic proton form factors at PANDA (FAIR) within the PandaRoot software framework are reported. The statistical precision with which the proton form factors can be determined is estimated. The signal channel p̄p → e+e− is studied on the basis of two different but consistent procedures. The suppression of the main background channel, i.e. p̄p...
