Feasibility studies of proton FF measurements in pp-collisions at PANDA — •Iris Zimmermann — Helmholtz-Institut Mainz

The investigation of the time-like electromagnetic form factors is one important goal of the PANDA-Experiment at the Facility of Antiproton and Ion Research (FAIR) at GSI. The data taking with high statistics at PANDA will allow the independent extraction of the time-like form factors from the study of the angular distribution of pp-collisions into a pair of charged leptons. The muonic channel contains the same physical information on the form factors as the electronic channel, but the difficult separation from the strong hadronic background makes that channel a big challenge. On the other hand the measurement of the muonic channel is a good opportunity to cross-check the results of the electronic channel. Therefore detailed simulation studies for both the muonic channel and the hadronic background (mostly pion production) are needed. First studies have been carried out to get a better understanding of the kinematical aspects of the muonic channel. The detailed simulation of those processes will be done using the software package PANDA Root taking the geometry and properties of the PANDA-Detector into account. Therefore an event generator for muons is under development.
