旋转质量矩阵、强CP问题与Higgs衰变

The Rotating Mass Matrix, the Strong CP Problem and Higgs Decay

Michael J Baker, S. T. Tsou

摘要:

我们调查最近的解决方案强CP问题,获得一个θ角的顺序统一,并表明,一个光滑的轨道的大规模的本征向量的秩1旋转质量矩阵是符合实验数据的费米子质量和混合角(除了最轻的夸克的质量)。使用这个轨迹,我们研究希格斯衰变,并发现抑制$Γ(H\to c\bar{c})$相比,标准模型的预测范围内的希格斯质量。我们也给味道违反衰变的限制,包括一个相对较大的分支比的$τ^-μ^+$模式。

英文摘要:

We investigate a recent solution to the strong CP problem, obtaining a theta-angle of order unity, and show that a smooth trajectory of the massive eigenvector of a rank-one rotating mass matrix is consistent with the experimental data for both fermion masses and mixing angles (except for the masses of the lightest quarks). Using this trajectory we study Higgs decay and find suppression of $Γ(H\to c\bar{c})$ compared to the standard model predictions for a range of Higgs masses. We also give limits for flavour violating decays, including a relatively large branching ratio for the $τ^-μ^+$ mode.
