Higgs粒子与$t$、$b$和$τ$的味对称耦合

Higgs Couplings to $t$, $b$, and $τ$ with Flavor Symmetry

Paul H. Frampton

摘要:

在大型强子对撞机上对可能存在的希格斯玻色子进行的实验研究应该很快就能提供汤川耦合$Y_{H\bar{f}f}$对$f=t,b,τ$的精确估计。在存在非阿贝尔离散味对称$G_F$(例如T ')的情况下,通常的预测$Y_{H\bar{f}f} \propto m_f$应该是不精确的,偏离它将通过$G_F$为改进夸克和轻子混合矩阵的推导提供有价值的输入。

英文摘要:

Experimental study at LHC of the possible Higgs boson should soon provide accurate estimates of the Yukawa couplings $Y_{H\bar{f}f}$ for $f=t,b,τ$. In the presence of a non-abelian discrete flavor symmetry $G_F$ (e.g. T') the usual prediction that $Y_{H\bar{f}f} \propto m_f$ should be inexact, and departures therefrom will provide through $G_F$ valuable input to an improved derivation of the quark and lepton mixing matrices.
