Abstract

The transverse momentum distributions of J/ψ mesons produced in pp collisions at the center-of-mass energy 5 TeV, 7 TeV, and 13 TeV are described by the modified Hagedorn function. The fitting results by the modified Hagedorn function are in accord with experimental data measured by the LHCb Collaboration at LHC. The related parameters are obtained and analyzed.
