Charmed baryon decays: $S U (3)_{F}$ breaking and CP violation

Chang Yang, Xiao-Gang He, Chia-Wei Liu

We present a comprehensive study of anti-triplet charmed baryon decays into octet baryons and pseudoscalar mesons using the $S U (3)_{F}$ flavor symmetry framework. By decomposing the…

Precise measurement of CP violating $τ$ EDM through $e^{+} e^{-} \to γ^{*}, ψ (2 s) \to τ^{+} τ^{-}$

Xiao-Gang He, Chia-Wei Liu, Jian-Ping Ma +2

A nonzero electric dipole moment of a tauon, $d_{τ}$ , signals CP violation and provides an important probe for new physics. We study methods to measure $d_{τ}$ at low energy $e^{+} e^{-}$ …
