$τ^{-} \to ω π^{-} ν_{τ}$ decay in R $χ$ T with tensor sources

Feng-Zhi Chen, Xin-Qiang Li, Yuan-He Zou

We present a study of the $τ^{-} \to ω π^{-} ν_{τ}$ decay in the framework of low-energy effective field theory. By analyzing the $J^{P G}$ quantum numbers of the quark currents and the $ωπ…

Study of $η^{'} \to η π π$ Decays in Large- $N_{C}$ Chiral Perturbation Theory

Feng-Zhi Chen, Xin-Qiang Li, Ya-Dong Yang +1

We investigate the $η^{'} \to η π π$ decays within the framework of large- $N_{C}$ chiral perturbation theory, by calculating the decay amplitudes up to next-to-next-to-leading ord…

Study of $τ^{-} \to ω π^{-} ν_{τ}$ decay in resonance chiral theory with tensor sources

Feng-Zhi Chen, Xin-Qiang Li, Shi-Can Peng +2

In this work, we make a study of the $τ^{-} \to ω π^{-} ν_{τ}$ decay in the framework of low-energy effective field theory. The $J^{P G}$ decompositions of the quark currents and…

Feng-Zhi Chen, Xin-Qiang Li

We present here the CP asymmetries in the decay rate and angular distributions of $τ \to K_{S} π ν_{τ}$ decays in the Standard Model (SM) and beyond (BSM). The CP asymmetries in the SM ar…
