CP violation studies at Super Tau-Charm Facility

Hai-Yang Cheng, Zhi-Hui Guo, Xiao-Gang He +16

Charge-parity ( $C P$ ) violation in the tau-charm energy region is a promising area for sensitive tests of Standard Model (SM) predictions and searches for new, beyond the SM physi…

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 $e^{+} e^{-}$ …

Impact of parity violation on quantum entanglement and Bell nonlocality

Yong Du, Xiao-Gang He, Chia-Wei Liu +1

Quantum entanglement (QE), evidenced by Bell inequality (BI) violations, reveals the nonlocality of nature. Fundamental interactions manifest in various forms, each with distinct e…

Fundamental Tests of P and CP Symmetries Using Octet Baryons at the $J / ψ$ Threshold

Yong Du, Xiao-Gang He, Jian-Ping Ma +1

We systematically investigate tests of the parity P and the combined parity and charge-conjugate CP symmetries from differential angular distributions of $J / ψ$ decaying into the lo…

Parity, Charge Conjugation and SU(3) Constraints on Threshold Enhancement in $J / ψ$ decays into $γ p p ˉ$ and $K p Λ ˉ$

Xiao-Gang He, Xue-Qian Li, J. P. Ma

We study the threshold enhancement effects of baryon-anti-baryon systems in $J / ψ$ decays at BES using parity $P$ , charge conjugation $C$ , and flavor SU(3) symmetries. The $P$ and $…

CP violation in $J / ψ \to Λ Λ ˉ$

Xiao-Gang He, J. P. Ma, B. McKellar

We study CP violation in $J / ψ \to Λ Λ ˉ$ decay. This decay provides a good place to look for CP violation. Some observables are very sensitive to the $Λ$ electric dipole mo…
