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...

| Summary: | 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 scheme for matching cross section and description of J/ψ production in a domain of intermediate transverse momenta. We also provide prediction for J/ψ production using fitted matrix elements at the kinematics of SPD NICA. |
