论文摘要
在这项研究中，我们研究了Fermilab（Fnal）报道的MUON $（G_μ-2）$的异常磁矩，以及CDF-II协作最近对$ W $ -BOSON质量的测量。这两个发现都均与标准模型（SM）的预测有很大的偏差，这暗示了新物理学的可能性。我们的重点是III型两-higgs-doublet模型（2HDM），其中两个希格斯双重夫妇与所有费米子夫妇，从而导致在树水平上诱导了改变风味的中性电流（FCNC）。在此框架内，我们研究了Lepton-Flavour-violating（LFV）方案，旨在解释这两个观察到的异常情况，同时满足最新的理论和实验性约束。
In this study, we investigate the anomalous magnetic moment of the muon $(g_μ-2)$ as reported by Fermilab (FNAL), along with the recent measurement of the $W$-boson mass by the CDF-II collaboration. Both findings show significant deviations from the predictions of the Standard Model (SM), hinting at the possibility of new physics. Our focus is on the Type III two-Higgs-doublet model (2HDM), wherein both Higgs doublets couple with all fermions, leading to the induction of flavour-changing neutral currents (FCNCs) at the tree level. Within this framework, we investigate a lepton-flavour-violating (LFV) scenario, aiming to explain both observed anomalies, while satisfying the up-to-date theoretical and experimental constraints.
