摘要：
The paper discusses the two-loop (NNLO) electroweak radiative corrections to the parity-violat-ing Møller scattering asymmetry induced by insertions to boxes of electron and neutrino mass operators (fer-mion 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. © 2015, Pleiades Publishing, Ltd.
