Electroweak Interaction and Baryogenesis

电弱重子发生取决于在一阶相变中产生的泡壁的轮廓。指出泡壁上的CP违和（过渡CP违和）可以变得足够大，以解释宇宙的重子不对称性（BAU）。在最小超对称模型（MSSM）中，两个希格斯双重粒子的有效势控制了具有CP违逆的泡壁轮廓。通过求解具有单环有效势的希格斯场在跃迁温度Tc下的运动方程，我们指出了跃迁CP违逆的发生。这种类型的CP破坏只存在于被泡壁隔开的对称相和破缺相之间的中间区域，并不与CP破坏的实验边界相矛盾。我们还发现，与中子电火花加工上的现有束缚相一致的微小显CP违背1，可以无扰动地解决cf共轭气泡对之间的简并，从而在相变后留下足够的BAU。我们必须强调，CF对称性从根本上来说是好的，贡献BAU的过渡CP违背被微小的显式CP违背所增强。

Electroweak baryogenesis depends on the profile of the bubble wall created in the first-order phase transition. It was pointed out that CP violation on the bubble wall(transitional CP violation) could become large enough to explain the baryon asymmetry of the universe(BAU). The profile of the bubble wall with CP violation is controlled by the effective potential of the two Higgs doublets in the minimal supersymmetric model(MSSM). We pointed out that the transitional CP violation really occurs by solving the equations of motion for the Higgs fieldswith the one loop effective potential at the transition temperature Tc.This type of CF violation exists only in the intermediate region between symmetric and broken phases separated by the bubble wall and never contradicts the experimental bounds on CP violation.We also showed that a tiny explicit CP violation1 which is consistent with the present bound on the neutron EDM, does nonperturbatively resolve the degeneracy between the CF-conjugate pair of bubbles to leave a sufficient BAU after the phase transition.We must stress that CF symmetry is fundamentally good and the transitional CP violation to contribute BAU is enhanced by a tiny explicit CP violation.
