论文摘要
彩色八位字的异构套件可以具有深奥的起源，并且符合最小的侵犯风味。在这项研究中，我们采用了一种场景，其中众所周知的type-X Type-X-Higgs Doublet模型通过颜色八位字等位roublet增强。我们阐明了这种设置如何预测$ w $ boson质量的最近观察到的价值。我们还评估了来自彩色标量的Muon $ G-2 $的两环Barr-Zee贡献。与观察到的MUON $ G-2 $兼容的参数空间得到了放松的W.R.T.由于彩色标量的贡献，它在纯X型2HDM中是什么。因此，扩展参数区域成功地说明了$ w $ sass和muon $ g-2 $异常。最后，使用基于剪切的和多变量的技术在14个TEV LHC上探索了$τ^+τ^-b \ bar {b} $最终状态的对撞机签名。这样的信号可以证实该框架引入的无色标量的存在。
A color octet isodoublet can have esoteric origins and it complies with minimal flavour violation. In this study, we take a scenario where the well known Type-X Two-Higgs doublet model is augmented with a color octet isodoublet. We shed light on how such a setup can predict the recently observed value for the $W$-boson mass. We also evaluate the two-loop Barr-Zee contributions to muon $g-2$ stemming from the colored scalars. The parameter space compatible with the observed muon $g-2$ gets relaxed w.r.t. what it is in the pure Type-X 2HDM by virtue of the contribution from the colored scalars. The extended parameter region therefore successfully accounts for both the $W$-mass and muon $g-2$ anomalies successfully. Finally, a collider signature leading to $τ^+ τ^- b \bar{b}$ final state is explored at the 14 TeV LHC using both cut-based and multivariate techniques. Such a signal can confirm the existence of both colorless as well colored scalars that are introduced by this framework.
