规范-希格斯统一中由于味混合引起的CP破坏

CP Violation due to Flavor Mixing in Gauge-Higgs Unification

Yuki Adachi, Nobuaki Kurahashi, Nobuhito Maru, Kazuya Tanabe

摘要:

我们讨论了五维$SU(3) \otimes SU(3)_{\rm color}$规范-希格斯统一方案中的CP破坏,其中第五维在轨道$S^1 /Z_2$上是紧化的。结果表明,CP破坏相甚至出现在两个世代的情况下,相反,事实上,至少需要三个世代打破CP对称性的标准模型。作为我们的预言,我们通过比较典型的CP破坏观测量,即$\varepsilon_K$参数和两个中性$K$介子$Δm_K$的质量差与实验数据,得到了对紧化尺度的唯象约束.

英文摘要:

We discuss CP violation in the five dimensional $SU(3) \otimes SU(3)_{\rm color}$ gauge-Higgs unification scenario in which the fifth dimension is compactified on an orbifold $S^1 /Z_2$. It is shown that CP-violating phase appears even in the two generation case in contrast with the fact that at least three generations are required to break CP symmetry in the Standard Model. As our prediction, we obtain the phenomenological constraint on the compactification scale by comparing the typical CP-violating observables, namely $\varepsilon_K$ parameter and the mass difference of two neutral $K$ mesons $Δm_K$ with experimental data.
