Probing double parton scattering via associated open charm and bottom production in ultraperipheral pA collisions
(2019) In European Physical Journal C 79(10).- Abstract
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 factorized DPS pocket formula. We have made the corresponding theoretical predictions for the DPS contribution to this process at typical LHC energies and beyond and we compute the energy-independent (but photon momentum fraction dependent) effective cross section.
