两圈水平上的变味中性标量相互作用

Brief description of the flavor-changing neutral scalar interactions at two-loop level

R. Gaitán, J. A. Orduz-Ducuara

摘要:

在这封信中,我们展示了一个一般性的描述,味道改变中性电流(FCNC)介导的标量。分析扩展到两个循环水平的两希格斯双重模型III型,因为其他模型有很强的约束,即使在高阶的扰动。在这封信中,我们将重点放在标准模型上,计算$h \to γγ$过程的振幅,并简要讨论结果。

英文摘要:

In this letter we show a general description about flavor-changing neutral currents (FCNC) mediated by scalars. The analysis is extended at two-loop level for the Two-Higgs Doublet Model type-III because others models have strong constraints on its parameters, even at high orders of the perturbation. For this letter we focus on the standard model, calculating the amplitude for the $h \to γγ$ process and discussing the results briefly.
