η transitions between charmonia with meson loop contributions

Dian-Yong Chen, Xiang Liu, Takayuki Matsuki

We study the $η$ transitions between $ψ (4040/4160)$ and $J / ψ$ by introducing charmed meson loops in an effective Lagrangian approach to enhance the decay amplitudes. The branching…

Does the enhancement observed in $γ γ \to D D ˉ$ contain two $P$ -wave higher charmonia?

Dian-Yong Chen, Jun He, Xiang Liu +1

Solved is a new puzzle raised by the observation of an enhancement structure Z(3930) in $γ γ \to D D ˉ$ . If categorizing Z(3930) as $χ_{c 2} (2 P)$ suggested by Belle and BaBar, we m…

Nonresonant explanation for the Y(4260) structure observed in the $e^{+} e^{-} \to J / ψ π^{+} π^{-}$ process

Dian-Yong Chen, Jun He, Xiang Liu

In this work, we proposed a nonresonant explanation for the Y(4260) structure observed in the $e^{+} e^{-} \to J / ψ π^{+} π^{-}$ process, i.e., Y(4260) is not a genuine resonance. Our result in…

$Δ$ contribution in $e^{+} + e^{-} \to p + p ˉ$ at small $s$

Hai Qing Zhou, Dian Yong Chen, Yu Bing Dong

Two-photon annihilate contributions in the process $e^{+} + e^{-} \to p + p ˉ$ including $N$ and $Δ$ intermediate are discussed in a simple hadronic model. The corrections to the u…
