Production of J/ψ within the Soft Gluon Resummation Approach and Nonrelativistic QCD

Production of J/ψ within the Soft Gluon Resummation Approach and Nonrelativistic QCD

In our study we analyse prompt J/ψ production in proton-proton collisions within the Soft Gluon Resummation approach, collinear parton model and nonrelativistic QCD. We extract a set of long-distance matrix elements for octet color states from experimental data at √s = 200 GeV. We use the InEW schem...
