论文摘要
使用2HDM的几何描述，我们将CP不变性分类为三个独立的部门，例如标量电势，Yukawa相互作用和CKM矩阵。 2HDM的热有效电位以基本不变方式计算。结果表明，Yukawa相互作用中的CP违规行为可以在一个循环水平上有效潜力，但是CKM矩阵中的CP阶段在所有秩序上都不能泄漏到有效潜力。在具有柔软损坏的Z_2对称性的2HDM中，领先的热校正倾向于在高温下恢复CP对称性。
Using a geometric description of 2HDM, we classify CP invariants into three independent sectors such as scalar potential, Yukawa interaction and CKM matrix. Thermal effective potential of 2HDM is calculated in a basis invariant way. It is shown that the CP violation in Yukawa interactions can contribute to effective potential at one loop level but the CP phase in the CKM matrix cannot leak to effective potential at all orders. In the 2HDM with a softly broken Z_2 symmetry, the leading thermal correction tends to restore the CP symmetry at high temperature.
