论文摘要
在这项工作中，我们将所有有效的$ U（1）$对称性及其在标准模型（SM）中的相关NOETHER分类及其最小的超对称扩展（MSSM）从通货膨胀后的最高规模降低到弱规模。然后，我们证明，发现违反Baryon减去Lepton数字（$ B-L $）的发现，这在任何宇宙温度以上的任何宇宙温度以高于$ 30 $ tev $ 30的范围内都违反，将在这些有效的指控中打开一个新的男性生成窗口。虽然早期宇宙中快速的SM巴里昂违规行为可能是解决宇宙巴里昂不对称难题的第一个作品，但$（b-l）$违规可能是第二个重要的部分。在扩展宇宙的背景下，有足够的平衡过程有足够的机会在SM或MSSM中产生众多有效电荷的不对称性，这使得几乎不可避免地使得Baryon不对称宇宙几乎不可避免。最后，我们在SM和MSSM中提供了示例，在不明确破坏Baryon或Lepton数字的情况下，Baryogenys可以通过平衡动力学进行。
In this work, we classify all the effective $U(1)$ symmetries and their associated Noether charges in the Standard Model (SM) and its minimal supersymmetric extension (MSSM) 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 ($B-L$) which pinpoints to its violation in primordial Universe at any cosmic temperature above $30$ TeV will open up a new window of baryogenesis in these effective charges above this scale. While the fast SM baryon number violation in the early Universe could be the first piece to solve the puzzle of cosmic baryon asymmetry, $(B-L)$ violation could be the second important piece. In the background of expanding Universe, there is ample opportunity for out-of-equilibrium processes to generate an asymmetry in the numerous effective charges in the SM or the MSSM, making a baryon asymmetric Universe almost unavoidable. Finally we provide examples in the SM and the MSSM where baryogenesis can proceed through out-of-equilibrium dynamics without explicitly breaking baryon nor lepton number.
