Two-photon exchange effects in $e^{+} e^{-} \to π^{+} π^{-}$ at small $s$

Zhong-Hua Zhao, Hui-Yun Cao, Hai-Qing Zhou

In this work, the two-photon-exchange (TPE) effects in $e^{+} e^{-} \to π^{+} π^{-}$ at small $s$ are discussed within a hadronic model. In the limit $m_{e} \to 0$ , the…

Decay widthes of $^{3} P_{J}$ charmonium to $D D, D D^{}, D^{} D^{*}$ and corresponding mass shifts of $^{3} P_{J}$ charmonium

Hui-Yun Cao, Hai-Qing Zhou

In this work, we calculate the amplitudes of the processes $c c ˉ (^{3} P_{J}) \to D D, D D^{*}, D^{*} D^{*} \to c c ˉ (^{3} P_{J})$ in the leading order of the nonrelativistic e…

Mass shifts of $^{3} P_{J}$ heavy quarkonia due to the effect of two-gluon annihilation

Hui-Yun Cao, Hai-Qing Zhou

In this work, we calculate the nonrelativistic asymptotic behavior of the amplitudes of $q q \to 2 g \to q q$ in the leading order of $α_{s}$ (LO-$α…

Correction to the energy spectrum of $^{1} S_{0}$ heavy quarkonia due to two-gluon annihilation effect

Hui-Yun Cao, Hai-Qing Zhou

In this work, the non-relativistic asymptotic behavior of the transition $q q \to 2 g \to q q$ in the $^{1} S_{0}$ channel is discussed. Different with t…
