Precise measurements of the proton electromagnetic form factors in the time-like region are planned at the future PANDA experiment at FAIR using the p p → ℓ+ ℓ− (ℓ=e, µ) annihilation processes. The feasibility of measuring these processes with the PANDA detector are investigated. Simulations on signal reconstruction efficiency and background rejection are performed using PANDARoot, the simulation and analysis software of the PANDA experiment. The expected precisions on the measurements of the proton form factors at PANDA are determined taking into account the staged approach for the detector setup and for the delivered luminosity from the accelerator. In addition, first order radiative corrections to the reaction p p → e+ e− are calculated including virtual and real photon emission. A Monte Carlo event generator to be used in the framework of the PANDA experiment is developed on the basis of the calculated radiative cross section. The results of these studies will be reported in this talk.
