Michel parameters for tau decays ... in a general two Higgs doublet model with mu - tau flavor violation

(ProQuest: ... denotes formulae and/or non-USASCII text omitted; see image).In a general two Higgs doublet model (2HDM), the anomaly of muon anomalous magnetic moment (muon g-2) can be explained by mu - tau flavor violating Yukawa couplings, motivated by the recent CMS excess in Higgs boson decay h arrow right mu tau . We study Michel parameters for tau decays ... in the 2HDM with the lepton flavor violation, and show that they can be sensitive to the flavor structure as well as the Lorentz and chiral structures of the model. We find that the correction to the Michel parameter xi sub( ) mu in ... is correlated to the contribution to the muon g-2, and it can be as large as 10 super( )-- 10 super( )-in the parameter region where the mu - tau flavor violating Yukawa couplings explain the muon g-2 anomaly. Therefore the precision measurement of the Michel parameter at the level of 10 super( )-- 10 super( )-would significantly probe the interesting parameter space for the solution to the muon g-2 anomaly.
