| 英文摘要 | We present measurements of the differential cross sections of inclusive J/psi meson production as a function of transverse momentum (p(T)(J/psi) ) using the mu(+)mu(-) 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 mu(+)mu(-) channel is for 0 < p(T)(J/psi) < 9 GeV/c and rapidity range vertical bar y(J/psi)vertical bar < 0.4, and that from the e(+)e(-) channel is for 4 < p(T)(J/psi) < 20 GeV/c and vertical bar y(J/psi)vertical bar < 1.0. The psi(2S) to J/psi ratio is also measured for 4 < p(T)(meson) < 12 GeV/c through the e(+)e(-) decay channel. Model calculations, which incorporate different approaches toward the J/psi production mechanism, are compared with experimental results and show reasonable agreement within uncertainties. |
