利用高温下反常电弱过程与B−L破坏相互作用之间的相互作用，我们导出了与中微子质量相关的界限，其尺度是早期宇宙中必然产生B−L不对称性的尺度。我们特别考虑了重右手中微子的非平衡衰变，以及标准模型的其他扩展中B−L破坏的影响。
Using the interplay between anomalous electroweak processes at very high temperatures and B−L violating interactions, we derive bounds, related to neutrino masses, on the scale at which a B−L asymmetry must have been produced in the early universe. We consider in particular, the out-of-equilibrium decays of heavy right-handed neutrinos, as well as the effects of B−L violation in other extensions of the standard model.
