NNLO electroweak corrections for polarized Moller scattering: one-loop insertions to boxes

Understand

The paper discusses the two-loop (NNLO) electroweak radiative corrections to the parity-violating Moller scattering asymmetry induced by insertions to boxes of electron and neutrino mass operators (fermion self-energies), vertex functions and boson self-energies.

• The results will be relevant to the ultra-precise 11 GeV MOLLER experiment planned at the Jefferson Laboratory, which will measure the weak charge of the electron and search for new physics.
• The numerical estimations for the NNLO contribution to the cross section asymmetry are presented.
