Impact of NNLO QED corrections on lepton-proton scattering at MUSE

Autor: Engel, T., Hagelstein, F., Rocco, M., Sharkovska, V., Signer, A., Ulrich, Y.

We present the complete next-to-next-to-leading order (NNLO) pure pointlike QED corrections to lepton-proton scattering, including three-photon-exchange contributions, and investigate their impact in the case of the MUSE experiment. These corrections
