Study of an anomalous tau lepton decay using a chiral Lagrangian with vector mesons

Daiji Kimura, Takuya Morozumi, Hiroyuki Umeeda

The hadronic tau decay $τ^{-} \to ν_{τ} η π^{-} π^{0}$ occurs through V-A weak current. In this decay mode, the vector current contribution is intrinsic parity violating and the axial curren…

Precise Discussion of Time-Reversal Asymmetries in B-meson decays

Takuya Morozumi, Hideaki Okane, Hiroyuki Umeeda

BaBar collaboration announced that they observed time reversal (T) asymmetry through $B$ meson system. In the experiment, time dependencies of two distinctive processes, $B_- \righ…
