DPS mechanism for associated cc¯ bb¯ production in AA UPCs

Huayra, Edgar ; de Oliveira, Emmanuel G. and Pasechnik, Roman LU (2020) In European Physical Journal C 80(8).
Abstract

We discuss the associated cc¯ and bb¯ quark pairs production in the double-parton scattering (DPS) process in ultraperipheral (UPCs) AA collisions. We derive an analogue of the inclusive DPS pocket formula and the photon-energy dependent effective cross section considering an overlap between the hard SPS scatterings. We provide numerical predictions for the DPS cross sections for the cc¯ bb¯ production process at the typical energies of AA UPCs at the LHC and FCC colliders and also characterize the A dependence of the total UPC DPS cross section.
