Probing the neutron-skin thickness through $J/\ddot{I}ˆ$ photoproduction in ultra-peripheral collisions

Haoyuan Li, Lu-Meng Liu, Jinhui Chen +2

We study the impact of neutron-skin thickness on $J/\ddot{I}ˆ$ photoproduction in ultra-peripheral ${}^{208}\mathrm{Pb}+{}^{208}\mathrm{Pb}$ collisions. Within the Color Glass Condensate fr…
