The PANDA experiment at the upcoming FAIR accelerator facility will study antiproton annihilation reactions at antiproton beam momenta between 1.5 GeV/c up to 30 GeV/c. Simulation results of the feasibility studies of time-like proton electromagnetic form factors at PANDA are presented. The simulation was performed using the PandaRoot software framework in a wide q2 range. The signal ppe+e and the background pp → π+π channels have been studied using two different methods. Individual signal efficiency and background suppression techniques were applied to extract the proton form factors. The statistical precision of the proton form factors extraction is determined. The results of two methods are consistent with each other. A number of systematic uncertainties have also been evaluated. The competitiveness of the PANDA experiment with existing data and planned experiments is presented.
