Probing double parton scattering via associated open charm and bottom production in ultraperipheral pA collisions
In this article, we propose a novel channel for phenomenological studies of the double-parton scattering (DPS) based upon associated production of charm cc¯ and bottom bb¯ quark pairs in well-separated rapidity intervals in ultraperipheral high-energy proton–nucleus collisions. This process provides direct access to the double-gluon distribution in the proton at small-x and enables one to test the
