Two Higgs doublet model with μ-τ flavor violation
A two Higgs doublet model (2HDM) is one of the minimal extensions of the standard model (SM), and it is well-known that the general set up predicts the flavor violating phenomena, mediated by Higgs interactions. The CMS collaboration has reported an excess of the lepton-flavor violating Higgs decay in h→μτ mode. We find that the μ-τ flavor violation in the 2HDM can explain not only the CMS excess in h→μτ but also an anomaly of the muon anomalous magnetic moment (muon g-2).
In this talk, we briefly explain this scenario, and show our results (predictions and constraints) in this scenario.
