Nature of $K^{*} (1680)$ and $q q ˉ$ -hybrid mixing as the SU(3) partner of $η_{1} (1855)$ in the strange sector

Samee Ullah, Ye Cao, Ming-Xiao Duan +2

We presents an investigation of the $K^{*} (1680)$ state in its strong decays into two-body finial states within the flux-tube model and quark pair creation model. Since the charge co…

Singly Cabibbo-suppressed hadronic weak decays of the $Ω^{-}$ hyperon

Ye Cao, Tao Zhong, Ju-Jun Xie +1

We study the two-body hadronic weak decays of the $Ω^{-}$ hyperon with strangeness $S = - 3$ , including three singly Cabibbo-suppressed decay modes: $Ξ^{0} π^{-}$ , $Ξ^{-} π^{0}$ and $Λ K^{-}$ . The…

A unified approach for the hadronic weak decays of $Λ$ and $Σ^{\pm} \to N π$

Ye Cao, Ming-Xiao Duan, Zhong Tao +1

We provide a unified approach for the two-body hadronic weak decays of hyperons with $S = - 1$ , i.e. $Λ$ and $Σ^{\pm}$ , in the framework of the non-relativistic constitute quark model (…

$J / ψ$ photoproduction near threshold and signals for the hidden charm pentaquarks

Ming-Xiao Duan, Chang Gong, Lin Qiu +1

We study the $J / ψ$ photoproduction $γ p \to J / ψ p$ near threshold to investigate the role played by the open charm channels and possible signals from the hidden charm $P_{c}$ pentaquark…

Understanding the non-trivial isoscalar pseudoscalar structures in the $K_{S} K_{S} π^{0}$ spectra in the $J / ψ$ radiative decay

Yin Cheng, Lin Qiu, Qiang Zhao

Initiated by the recent observation of a flattened lineshape of $I J^{P C} = 0 0^{-+}$ around $1.4 \sim 1.5$ GeV in the $K_{S} K_{S} π^{0}$ invariant mass spectrum by BESIII, we make a systema…

Study of weak radiative decays of $D^{0} \to V γ$

Ye Cao, Qiang Zhao

The weak radiative decay of $D^{0} \to V γ$ with $V = K ˉ^{0}$ , and $ϕ$ , $ρ^{0}$ , and $ω$ , is systematically studied in the vector meson dominance (VMD) model. It allows us to distinguis…

Coupled-channel description of charmed heavy hadronic molecules within the meson-exchange model and its implication

Lin Qiu, Chang Gong, Qiang Zhao

Motivated by the first observation of the double-charm tetraquark $T_{cc}^{+} (3875)$ by the LHCb Collaboration, we investigate the nature of $T_{cc}^{+}$ as an isoscalar $D D^{*}$ hadroni…
