论文摘要
提出了由$τ$ Lepton Transper介导的电动性男性生成（EWBG）机制。我们使用真实的单线标量$ s $扩展标准模型，以触发强大的一阶电子相变（SFOEWPT），并使用一组瘦素尺寸-5操作员来提供足够的CP违反CP违反源。我们证明了该模型能够生成宇宙观察到的重子不对称。该方案在下一代空间探测器处的SFOEWPT重力波信号或$ pp \ to h^*\至ss \ to ss \ to4τ$过程（其中$ h^*$是一个off-shell higgs）在Hadron Colliders上可以通过实验测试。详细的对撞机模拟表明，可以在HL-LHC上探测很大一部分参数空间，而EWBG允许的几乎可以通过27 TEV HE-LHC达到的整个参数空间。
An electroweak baryogenesis (EWBG) mechanism mediated by $τ$ lepton transport is proposed. We extend the Standard Model with a real singlet scalar $S$ to trigger the strong first-order electroweak phase transition (SFOEWPT), and with a set of leptophilic dimension-5 operators to provide sufficient CP violating source. We demonstrate this model is able to generate the observed baryon asymmetry of the universe. This scenario is experimentally testable via either the SFOEWPT gravitational wave signals at the next-generation space-based detectors, or the $pp\to h^*\to SS\to 4τ$ process (where $h^*$ is an off-shell Higgs) at the hadron colliders. A detailed collider simulation shows that a considerable fraction of parameter space can be probed at the HL-LHC, while almost the whole parameter space allowed by EWBG can be reached by the 27 TeV HE-LHC.
