Probing CP Violation with Hyperon EDMs at BESIII

Jianyu Zhang

The prevalence of matter over antimatter in the observable universe remains one of the most profound puzzles in modern physics, necessitating sources of charge-parity (CP) symmetry…

Probing hyperon electric dipole moments with a full angular analysis

Jinlin Fu, Hai-Bo Li, Jian-Peng Wang +2

The electric dipole moment (EDM) of elementary particles, arising from flavor-diagonal $C P$ violation, serves as a powerful probe for new physics beyond the Standard Model and hold…

Measurement of $C P$ violation of neutral kaon system in $J / ψ$ decay at the Super Tau-Charm Facility

Jian-Yu Zhang, Cheng-Dong Fu, Hai-Bo Li +2

In this paper, we present a preliminary study of $C P$ violation effect of $K^{0} - K ˉ^{0}$ system in $J / ψ$ decay. The $C P$ violation parameters $η_{+-}$ and $η_{00}$ as well as…
