DPS mechanism for associated $c\bar{c}b\bar{b}$ production in $AA$ UPCs

Edgar Huayra, Emmanuel G. de Oliveira, Roman Pasechnik

We discuss the associated $c\bar{c}$ and $b\bar{b}$ quark pairs production in the double-parton scattering (DPS) process in ultraperipheral (UPCs) $AA$ collisions. We derive an ana…
