Obsah
We present a measurement of inclusive J/psi production at mid-rapidity (vertical bar y vertical bar < 1) in p+p collisions at a center-of-mass energy of root s = 200 GeV with the STAR experiment at the Relativistic Heavy Ion Collider (RHIC). The differential production cross section for J/psi as a function of transverse momentum (p(T)) for 0 < p(T) < 14 GeV/c and the total cross section are reported and compared to calculations from the color evaporation model and the non-relativistic Quantum Chromodynamics model. The dependence of J/psi relative yields in three p(T) intervals on charged-particle multiplicity at mid-rapidity is measured for the first time in p+p collisions at root s = 200 GeV and compared with that measured at root s = 7 TeV, PYTHIA8 and EPOS3 Monte Carlo generators, and the Percolation model prediction.
