论文摘要
时空奇偶校验可以解决强大的CP问题，并引入了自发损坏的$ SU（2）_r $ gauge对称性。我们研究了类似于electroweak baryogenogeny的一阶$ su（2）_r $相变的可能性。我们考虑了一个具有最小HIGGS含量的模型，为此，强大的CP问题确实可以解决，而没有引入超越平等的额外对称性。尽管平价对称性似乎禁止$ su（2）_r $ $ $ $对称性的异常，但费米昂群众的结构可以允许$ su（2）_r $ sphaleron过程生产非Zero $ b-l-l-l-l $ bl $ symmetry的标准模型的非零$不对称，从而使$ su（$ su（2）_l $ sphalan avo avo avo avo avo avo avo avo avo。该设置预测了一种新的超收费费用，其质量与$ su（2）_r $ symmetry breaking量表相关，因此与$ su（2）_r $ gauge boson质量相关，并取决于CP违规的起源，具有电子电动偶极时刻。在违反CP和一阶阶段过渡的设置中，可以通过单线标量尺寸辅助，可以在未来的围栏上搜索单元。
Space-time parity can solve the strong CP problem and introduces a spontaneously broken $SU(2)_R$ gauge symmetry. We investigate the possibility of baryogenesis from a first-order $SU(2)_R$ phase transition similar to electroweak baryogenesis. We consider a model with the minimal Higgs content, for which the strong CP problem is indeed solved without introducing extra symmetry beyond parity. Although the parity symmetry seems to forbid the $SU(2)_R$ anomaly of the $B-L$ symmetry, the structure of the fermion masses can allow for the $SU(2)_R$ sphaleron process to produce non-zero $B-L$ asymmetry of Standard Model particles so that the wash out by the $SU(2)_L$ sphaleron process is avoided. The setup predicts a new hyper-charged fermion whose mass is correlated with the $SU(2)_R$ symmetry breaking scale and hence with the $SU(2)_R$ gauge boson mass, and depending on the origin of CP violation, with an electron electric dipole moment. In a setup where CP violation and the first-order phase transition are assisted by a singlet scalar field, the singlet can be searched for at future colliders.
