论文摘要
我们将希格斯玻色子的罕见衰变重新审视到标准模型中的两个不同夸克，这是在一环水平上产生的。我们根据不同的质量层次结构对衰减振幅的完整形式进行泰勒系列的扩展，这使我们能够充分利用GIM机制来消除虚假贡献并保留真正贡献的贡献。我们发现br $（h \ to uc）$ = $ 5.00 \ times10^{ - 20} $，br $（h \ to ds）$ = $ 1.19 \ times10^{ - 11} $，br $（h \ to db to db）$ = $ = $ 5.16 \ times10 \ times10^times10^{ - 9} $ and Br $（n tipes $ and $（sb）我们对UC的$ H \的预测，DS $衰减不同意文献中的先前结果。
We revisit the rare decays of the Higgs boson to two different quarks in the Standard Model, which arise at the one-loop level. We perform Taylor series expansions to the complete form factors of the decay amplitudes, according to their different mass hierarchies, this allow us to take full advantage of the GIM mechanism to eliminate spurious contributions and retain those that truly contribute. We found that Br$(H\to uc)$=$5.00\times10^{-20}$, Br$(H\to ds)$=$1.19\times10^{-11}$, Br$(H\to db)$=$5.16\times10^{-9}$ and Br$(H\to sb)$=$1.15\times10^{-7}$. Our predictions for the $H\to uc,ds$ decays disagree with previous results in the literature.
