QED radiative corrections for Polarized Lepton-Proton Scattering

Abstract

We discuss QED radiative corrections at first and second order for the parity violating asymmetry APV in elastic electron proton scattering. A measurement of APV is planned at low energies and with high precision by the forthcoming P2 experiment at the new MESA facility in Mainz. Bremsstrahlung leads to a shift of the momentum transfer Q2 which affects the determination of the weak charge of the proton.
