Simulations studies have shown that the PANDA detector at FAIR will be capable of measuring the timelike electromagnetic form factors of the proton via the reaction pp → e⁺e⁻ with a precision of a few percent at low q², thus demanding to take into account radiative corrections. First order radiative corrections to pp → e⁺e⁻ have been calculated in the point-like approximation, including both virtual and real corrections, and interference effects. Suitable event generators to be used in the framework of the PANDA experiment have been developed on the basis of the calculated cross section.
