论文摘要
我们探讨了具有重纤维收缩阶段的可能性。快速滚动的ekpyrotic标量与标准模型超额度量规场之间的Chern-Simons耦合，使收缩阶段的非零螺旋性产生。随后在Electroweak相变处产生的重子数与观察一系列耦合和弹跳量表一致。同时，收缩期间的量规场的产生为银河磁场和来源重力波提供了种子，这可能为观察确认提供了其他途径。
We explore the possibility of an Ekpyrotic contraction phase harbouring a mechanism for Baryogenesis. A Chern-Simons coupling between the fast-rolling Ekpyrotic scalar and the Standard Model Hypercharge gauge field enables the generation of a non-zero helicity during the contraction phase. The baryon number subsequently produced at the Electroweak Phase Transition is consistent with observation for a range of couplings and bounce scales. Simultaneously, the gauge field production during the contraction provides the seeds for galactic magnetic fields and sources gravitational waves, which may provide additional avenues for observational confirmation.
