abstract
We perform updated and detailed calculations of the complete NLO set of electroweak radiative corrections to parity violating e- e- --> e- e- (gamma) scattering asymmetries at energies relevant for the ultra-precise Moller experiment coming soon at JLab. Our numerical results are presented for a range of experimental cuts and relative importance of various contributions is analyzed. We also provide very compact expressions analytically free from non-physical parameters and show them to be valid for fast yet accurate estimations.

Higher order electroweak radiative corrections in lepton-proton scattering using covariant approach
The authors compute one-loop, quadratic, and reducible two-loop electroweak corrections to the parity-violating asymmetry in elastic lepton-proton scattering and find percent-level NNLO effects at the kinematics of several planned experiments.
