Charged Higgs Flavor Changing Current in tau^- to nu_X K^- pi^0

Daiji Kimura, Kang Young Lee Takuya Morozumi Keita Nakagawa

We study the effect of flavor changing charged current(FCCC) of lepton sector in the hadronic tau decays, tau \to nu_X K^- pi^0 (X=e,mu). In general two Higgs doublet model, the le…

CP violation in tau decays

Daiji Kimura, Kang Young Lee, Takuya Morozumi +1

CP violation of the charged lepton sector has not been found yet. Tau is a unique charged lepton which can decay into hadrons. In this talk, we argue what kind of new physics can b…

CP violation of tau -> K pi(eta, eta') nu decays

Daiji Kimura, Kang Young Lee, T. Morozumi +1

We study direct CP violation of tau -> K pi(eta,eta')nu decays. By studying the forward and backward asymmetry, the interference of L=0 and L=1 amplitudes of the hadronic system ca…
