The precise measurements of the time-like electromagnetic form factors of the proton, expected at the future PANDA experiment via the reaction p p → e+ e−, require to take into account radiative corrections. In this work, first order radiative corrections to the reaction p p → e+ e− are calculated in the proton point-like approximation, including virtual and real photon emission. Soft and hard photon emission regimes are covered in the calculation. A Monte Carlo event generator is developed on the basis of the calculated radiative cross section and its application to the PANDA experiment is illustrated.
