论文摘要

由于$ w $ - 质量和muon $ g-2 $都会受到2hdm中额外的higgs玻色子$(H,〜a,〜h^\ pm)$之间的大量分割的影响,我们采用$μ$ - $ $ -UST-$τ$ LFV交互的型号,以检查CDF II和Fnals CDF II和fnals的两种Anomalies。我们获得以下观察结果:(i)结合理论约束,CDF $ W $ - 质量测量值$ h $ $ h $或$ a $以$ h^\ pm $的质量退化,但允许$ h $和$ h $和$ a $ n ementerate。 $ h^\ pm $和$ h/a $之间的质量分配必须大于10 GEV。 $ m_ {h^\ pm} $和$ m_ {a} $对于$ m_h <120 $ gev的650 GEV小于650 GEV,并允许具有更多的较大值,而增加了$ m_h $。 (ii)在强加其他相关的实验约束后,有一些参数空间同时满足($2σ$级别)CDF $ W $ - 质量,Fnal Muon $ G-2 $以及Lepton普遍性在$τ$衰减中的数据,但是在额外的HIGGS玻璃盆中的大规模划分严格受到约束。

Since both $W$-mass and muon $g-2$ can be affected by the mass splittings among extra Higgs bosons $(H,~A,~H^\pm)$ in a 2HDM, we take a model with $μ$-$τ$ LFV interactions to examine the two anomalies reported respectively by CDF II and FNAL. We obtain the following observations: (i) Combined with theoretical constraints, the CDF $W$-mass measurement disfavors $H$ or $A$ to degenerate in mass with $H^\pm$, but allows $H$ and $A$ to degenerate. The mass splitting between $H^\pm$ and $H/A$ is required to be larger than 10 GeV. The $m_{H^\pm}$ and $m_{A}$ are favored to be smaller than 650 GeV for $m_H<120$ GeV, and allowed to have more large values with increasing of $m_H$. (ii) After imposing other relevant experimental constraints, there are parameter spaces that simultaneously satisfy (at $2σ$ level) the CDF $W$-mass, the FNAL muon $g-2$ and the data of lepton universality in $τ$ decays, but the mass splittings among extra Higgs bosons are strictly constrained.
