摘要

在这项工作中,我们对标准模型及其超对称扩展中所有有效的$U(1)$对称性及其相关的Noether电荷进行了分类,从膨胀后的最高尺度降至弱尺度。然后我们证明,在$30$ TeV以上的任何尺度上重子-轻子数违反的发现,将为这些有效电荷在该尺度以上的重子发生打开一个新的窗口。我们还提供了几个例子,在没有明确打破重子和轻子数的情况下,重子发生可以通过非平衡动力学进行。

Baryogenesis in the standard model and its supersymmetric extension
In this work, we classify all the effective $U(1)$ symmetries and their associated Noether charges in the Standard Model and its supersymmetric extension from the highest scale after inflation down to the weak scale. We then demonstrate that the discovery of the violation of baryon minus lepton number at any scale above $30$ TeV will open up a new window of baryogenesis in these effective charges above this scale. We also provide several examples where baryogenesis can proceed through out-of-equilibrium dynamics without explicitly breaking baryon nor lepton number.
