Understanding the branching ratios of χ_{c1}\toϕϕ, ωω, ωϕobserved at BES-III

Dian-Yong Chen, Jun He, Xue-Qian Li +1

In this work, we discuss the contribution of the mesonic loops to the decay rates of $χ_{c 1} \to ϕϕ, ω ω$ which are suppressed by the helicity selection rules and $χ_{c 1} \to ϕ ω$ whi…

$Δ$ 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…
