Unified framework for heavy flavor and quarkonium production in high multiplicity p plus p and p plus A collisions at RHIC and LHC

摘要

We discuss the production of D-mesons and J/psi in high multiplicity proton-proton and proton-nucleus collisions within the Color-Glass-Condensate (CGC) framework. We demonstrate that the modification of the LHC data on D and J/psi yields in high multiplicity events relative to minimum bias events arise from a significant enhancement of the gluon saturation scales of the corresponding rare parton configurations in the colliding protons and nuclei. For a given event multiplicity, we predict these relative yields to be energy independent from root s = 200 GeV at RHIC to the highest LHC energies.
