Description
I will discuss a novel channel for phenomenological studies of the double-parton scattering (DPS) based upon associated production of charm and bottom quark-antiquark pairs in well-separated rapidity intervals in ultra-peripheral high-energy proton-nucleus collisions. This process provides a direct access to the double-gluon distribution in the proton at small-x and enables one to test the factorised DPS pocket formula. I will present the corresponding theoretical predictions for the DPS contribution to this process at typical LHC energies and beyond and validate the use of the energy-independent (but photon momentum fraction dependent) effective cross section.
