Lineshape of $e^{+} e^{-} \to D^{} D ˉ + c . c .$ and electromagnetic form factor of $D^{} \to D$ transition in the time-like region

Yuan-Jiang Zhang, Qiang Zhao

In this work, we apply the vector meson dominance (VMD) model to extract the electromagnetic time-like form factor of the $D^{*} \to D$ transition combining the recent Belle data for…

The lineshape of $ψ (3770)$ and low-lying vector charmonium resonance parameters in $e^{+} e^{-} \to D D ˉ$

Yuan-Jiang Zhang, Qiang Zhao

We investigate the $D D ˉ$ production in $e^{+} e^{-}$ annihilations near threshold in an effective Lagrangian approach. This shows that the lineshape of the cross section near thres…

A possible mechanism for producing the threshold enhancement in $J / ψ \to γ p p ˉ$

Xiao-Hai Liu, Yuan-Jiang Zhang, Qiang Zhao

In the $J / ψ$ radiative decay channels $J / ψ \to γ V V ˉ$ , the result of partial wave analysis indicates that the $V V ˉ$ systems are predominately pseudoscalar component, and mo…

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…

Study of isospin violating $ϕ$ excitation in $e^{+} e^{-} \to ω π^{0}$

Gang Li, Yuan-Jiang Zhang, Qiang Zhao

We study the reaction $e^{+} e^{-} \to ω π^{0}$ in the vicinity of $ϕ$ mass region. The isospin-violating $ϕ$ excitation is accounted for by two major mechanisms. One is electromagnetic (E…
