Description
We assess the theoretical uncertainties on the inclusive J/psi production
cross section in the Color Evaporation Model using values for the charm quark
mass, renormalization and factorization scales obtained
from a fit to the charm production data [1]. We use our new results to provide
improved baseline comparison calculations at RHIC and the LHC. We calculate
the fraction of J/psi production from B decays as a function of pT
with these parameters. We also study cold matter effects on J/psi
production at leading relative to next-to-leading order in the CEM within this
approach [2].
