Radiative corrections in proton–antiproton annihilation to electron–positron and their application to the PANDA experiment: Radiative corrections to $${\bar{p}} p \rightarrow e^+e^-$$p¯p→e+e-

Radiative corrections to the annihilation of proton–antiproton into electron–positron are revisited, including virtual and real (soft and hard) photon emission. This issue is relevant for the time-like form factors measurements planned at the PANDA experiment at the FAIR facility, in next future. The relevant formulas are given. A stand-alone Monte-Carlo integrator is developed on the basis of the calculated radiative cross section and its application to the PANDA experiment is illustrated.
