The Cabibbo-favored hadronic weak decays of the $Ξ_{c}$ in the quark model

Peng-Yu Niu, Qian Wang, Qiang Zhao

The Cabibbo-favored hadronic weak decay of the $Ξ_{c}^{+} \to Ξ^{0} π^{+}$ , $Ξ_{c}^{0} \to Ξ^{-} π^{+}$ , $Ξ_{c}^{0} \to Ξ^{0} π^{0}$ , $Ξ_{c}^{0} \to Ξ^{0} η^{(^{'})}$ and $Ξ_{c}^{0} \to Ξ^{+} K^{-}$ are studied in the non-relativis…

Hyperon Weak Radiative Decay

Peng-Yu Niu, Jean-Marc Richard, Qian Wang +1

We revisit the hyperon weak radiative decays in the framework of the non-relativistic constituent quark model. This study confirms the nonlocal feature of the hyperon weak radiativ…

Hadronic weak decays of $Λ_{c}$ in the quark model

Peng-Yu Niu, Jean-Marc Richard, Qian Wang +1

The hadronic weak decays of $Λ_{c}$ are studied in the framework of a constituent quark model. With the combined analysis of the Cabbibo-favored processes, $Λ_{c} \to Λ π^{+}$ , $Σ^{0} π^{+}$ an…

The mass splitting among the isospin multiplets of light vector mesons

Peng-Yu Niu, Bin Zhou, Qiang Zhao

By including the strong isospin symmetry breaking effects and the electromagnetic contributions between the pseudoscalar mesons, we calculate the phase shifts of the $P$ -wave $π π$ …
