New sum rules from exact -spin degeneracy

Chao-Qiang Geng, Chia-Wei Liu, Sheng-Lin Liu +1

We propose a new class of sum rules in the -spin limit, based on the observation that the weak phase in the Standard Model can be removed in the degenerate limit .…

Probing the imaginary parts and their dependences for the tau and EDM

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

The anomalous magnetic dipole moment (MDM) and electric dipole moment (EDM) , are precision probes of electroweak dynamics and possible new physics so…

Spin-flavor entanglement in and weak phase extraction

Yong Du, Chao-Qiang Geng, Xiao-Gang He +3

We identify a new spin-flavor entanglement structure in decays, formed by the correlation between the spin and the flavor states ($D=D^0,\overline D^0,D_1,D_2…

Charmed baryon decays: 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 flavor symmetry framework. By decomposing the…

Large CP violation in charmed baryon decays

Xiao-Gang He, Chia-Wei Liu

This work presents the first detailed numerical predictions of CP violation in antitriplet charmed baryon decays. Adopting the flavor symmetry and the final state re-scat…

Large CP violation in 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 -baryon decay . This is the first observation of CP violation in ba…
