Abstract

For a quark-gluon plasma to form in nuclear collisions, the resulting partonic medium must be dense, and its constituents must interact. The authors examined proton-proton collisions at LHC energies, and focused on the production of charm quarks, since these are only produced in hard perturbative QCD interactions. The results indicate the formation of an interacting medium that is dense enough for the suppression of radiation to set in and yet permits multiple scatterings among partons. Their study shows the importance of multiple parton interactions even in proton-proton collisions.
