内容記述 | We present measurements of the differential cross sections of inclusive J/ψ meson production as a function of transverse momentum (pJ/ψT) using the μ+μ? and e+e? decay channels in proton+proton collisions at center-of-mass energies of 510 and 500 GeV, respectively, recorded by the STAR detector at the Relativistic Heavy Ion Collider. The measurement from the μ+μ? channel is for 0<pJ/ψT<9??GeV/c and rapidity range |yJ/ψ|<0.4, and that from the e+e? channel is for 4<pJ/ψT<20??GeV/c and |yJ/ψ|<1.0. The ψ(2S) to J/ψ ratio is also measured for 4<pmesonT<12??GeV/c through the e+e? decay channel. Model calculations, which incorporate different approaches toward the J/ψ production mechanism, are compared with experimental results and show reasonable agreement within uncertainties. | |||||
