Exclusive production in ultraperipheral ion collisions
Zi-Qiang Chen, Long-Bin Chen
Ultraperipheral collisions (UPCs) of ions provide new opportunities to study the quarkonium production mechanism in photon-photon scattering. In this paper, we investigate the excl…

Charmonium pair production in ultraperipheral collision
Hao Yang, Zi-Qiang Chen, Bingwei Long
We study the exclusive double charmonium ($J/Ï\mbox{-} J/Ï$ and $η_c \mbox{-} η_c$) production through photon-photon fusion via ultraperipheral collision (UPC) at the HL-LHC an…
