Nonstandard Solution for Anomaly Cancellation as Seesaw Neutrino Origin in the SM

Zi-Yue Zou, Chia-Wei Liu, Zhong-Lv Huang +1

For fixed Standard Model (SM) non-Abelian representations of 15 chiral fermions with arbitrary hypercharges, anomaly cancellation admits the usual assignment and a distinct nonstan…

Probing the imaginary parts and their $q^{2}$ dependences for the tau $g - 2$ and EDM

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

The $τ$ anomalous magnetic dipole moment (MDM) $a_{τ} = (g - 2)_{τ} /2$ and electric dipole moment (EDM) $d_{τ}$ , are precision probes of electroweak dynamics and possible new physics source…

Spin-flavor entanglement in $Λ_{b} \to Λ D$ and weak phase extraction

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

We identify a new spin-flavor entanglement structure in $Λ_{b} \to Λ D$ decays, formed by the correlation between the $Λ$ spin and the $D$ flavor states ( $D = D^{0}, D^{0}, D_{1}, D_{2}$ ).…

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…
