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…

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…

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…
