Fine Splitting in Charmonium Spectrum with Channel Coupling Effect

Chun Yang, Bao-Fei Li, Xiao-Lin Chen +1

We study the fine splitting in charmonium spectrum in quark model with the channel coupling effect, including $DD$, $D{D}^{\ast }$, $D^{\ast }{D}^{\ast }$ and $D_s{D}_s$, $D_s{D}_s^{\ast }$, $D_s^{\ast }{D}_s^{\ast }$ channels…
