J/ψ production in e + p collisions in the improved color evaporation model
ORAL
Abstract
One of the best ways to understand hadronization in QCD is to study the production of quarkonium. The color evaporation model (CEM) and Nonrelativistic QCD (NRQCD) can describe production yields rather well but spin-related measurements like the polarization are stronger tests. After demonstrating the utility of the ICEM for quarkonium production and polarization in hadronic collisions, in this talk, we will present recent results in the improved color evaporation model (ICEM) in e + p collisions.
