Complex $τ$ Electric Dipole Moment from GeV-Scale New Physics

Zhong-Lv Huang, Xin-Yu Du, Xiao-Gang He +2

Among the charged leptons, the $τ$ electric dipole moment~( $d_{τ}$ ) is the least constrained. We show that the Im[ $d_{τ}$ ] imposes strong constraints on new physics that have yet to be…

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…

Large CP violation in $Λ_{b}^{0} \to p K^{-} π^{+} π^{-}$ and its U-spin partner decays

Xiao-Gang He, Chia-Wei Liu, Jusak Tandean

The LHCb Collaboration has recently found a large CP-violating rate asymmetry in the $b$ -baryon decay $Λ_{b}^{0} \to p K^{-} π^{+} π^{-}$ . This is the first observation of CP violation in baryo…

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 $e^{+} e^{-}$ …
