Towards a dynamical understanding of the non- $D D ˉ$ decay of $ψ (3770)$

Yuan-Jiang Zhang, Gang Li, Qiang Zhao

We investigate the $ψ (3770)$ non- $D D ˉ$ decays into $V P$ , where $V$ and $P$ denote vector and pseudoscalar mesons, respectively, via OZI-rule-evading intermediate meson rescatt…

Possible contributions to $e^{+} e^{-} \to J / ψ + η_{c}$ due to intermediate meson rescatterings

Yuan-Jiang Zhang, Qiang Zhao, Cong-Feng Qiao

Inspired by the obvious discrepancies between experiment and non-relativistic QCD (NRQCD) studies of $e^{+} e^{-} \to J / ψ + η_{c}$ at $s ≃ 10.6$ GeV, we investigate contributions…

Search for tetraquark candidate Z(4430) in meson photoproduction

Xiao-Hai Liu, Qiang Zhao, Frank E. Close

We propose a search for the newly discovered tetraquark candidate Z(4430) in photoproduction. Based on the Belle results we show that if Z(4430) is a genuine resonance, its signifi…

Strong decays of heavy-light mesons in a chiral quark model

Xian-hui Zhong, Qiang Zhao

We carry out a systematic study of the heavy-light meson strong decays in a chiral quark model. For the $S$ -wave vectors ( $D^{*} (2007)$ , $D^{*\pm} (2010)$ ), $P$ -wave scalars ($D^*_0(2…

Charmed baryon strong decays in a chiral quark model

Xian-Hui Zhong, Qiang Zhao

Charmed baryon strong decays are studied in a chiral quark model. The data for the decays of $Λ_{c}^{+} (2593)$ , $Λ_{c}^{+} (2625)$ , $Σ_{c}^{++, +, 0}$ and $Σ_{c}^{+, 0} (2520)$ , are accounted for s…

Hadronic loop contributions to $J / ψ$ and $ψ^{'}$ radiative decays into $γ η_{c}$ or $γ η_{c}^{'}$

Gang Li, Qiang Zhao

Intermediate hadronic meson loop contributions to $J / ψ$ , $ψ^{'} \to γ η_{c}$ ( $γ η_{c}^{'}$ ) are studied apart from the dominant M1 transitions in an effective Lagrangian approach.…
