DPS mechanism for associated $c\bar{c}{l}^{+}{l}^{-}$ production in $AA$ UPCs as a probe for photon density inside the nucleus

Edgar Huayra, Emmanuel G. de Oliveira, Roman Pasechnik +1

We discuss the associated $c\bar{c}$ and $l^{+}{l}^{-}$ pairs production in ultraperipheral heavy-ion collisions at high energies. Such a channel provides a novel probe for double-parton…
