Heavy quark pair production in high energy pA collisions: Open heavy flavors

Understand

We study open heavy flavor meson production in proton-nucleus (pA) collisions at RHIC and LHC energies within the Color Glass Condensate framework.

• We use the unintegrated gluon distribution at small Bjorken's x in the proton obtained by solving the Balitsky-Kovchegov equation with running coupling correction and constrained by global fitting of HERA data.
• We change the initial saturation scale of the gluon distribution for the heavy nucleus.
• The gluon distribution with McLerran-Venugopalan model initial condition is also used for comparison.
