本文讨论了由电子和中微子质量算符（费米子自能）、顶点函数和玻色子自能引入盒中引起的宇称破坏Møller散射不对称性的双圈（NNLO）电弱辐射修正。这些结果将与杰斐逊实验室计划的超精密11 GeV MOLLER实验有关，该实验将测量电子的弱电荷并寻找新的物理学。给出了NNLO对截面不对称性的贡献的数值估计。
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.
