论文摘要
颜色量表标量在各种大统一场景中以及其他新物理学模型中都出现。他们还假定违反风味的情况。因此，纯粹的现象学烙印值得一看。在此激励的基础上，我们在两个Higgs Doublet模型中进行了$ h^+ \ to w^+ z（\ g）$衰减的完整一环计算，该计算由color-octet $ su（2）_l $ scalar doublet增强。该计算方便地分离为无色和彩色组件。幅度的颜色octet部分由颜色因子缩放，为形式因素提供了总体增强。从扰动单位性，标量电位的阳性，倾斜参数，HIGGS信号强度以及直接搜索带电的Higgs和Color-Octet标量的关键约束都折叠为分析。阐明了循环诱导的$ h^+ \对w^+ z（\ g）$顶点对其他模型参数的敏感性。最后，还讨论了将来在将来的Hadronic Collions中观察循环引起的$ h^+ \ to w^+ z（\ g）$相互作用的前景。
Color-octet scalars arise in various Grand Unification scenarios and also in other models of new physics. They are also postulated for minimal flavour violation. Purely phenomenological imprints of such scalars are therefore worth looking at. Motivated by this, we perform a complete one-loop calculation of the $H^+ \to W^+ Z (\g)$ decay in a two Higgs doublet model augmented by a color-octet $SU(2)_L$ scalar doublet. The computation is conveniently segregated into colorless and colored components. The color-octet part of the amplitude, being scaled by the color-factor, provides an overall enhancement to the form factors. Crucial constraints from perturbative unitarity, positivity of the scalar potential, oblique parameters, Higgs signal strengths and direct search of a charged Higgs and color-octet scalars are folded-in into the analysis. Sensitivity of the loop-induced $H^+ \to W^+ Z (\g)$ vertex to other model parameters is elucidated. Finally, the prospect of observing a loop-induced $H^+ \to W^+ Z (\g)$ interaction at the future hadronic collisions is also discussed.
