摘要：
The transverse momentum spectra of pi(+/-) mesons, protons and antiprotons produced in proton-proton collisions at 200 GeV with hadron production models are reported. Two tunes of EPOS (EPOS1.99 and EPOS-LHC), three tunes of QGSJET (QGSJETI, QGSJETII-03, QGSJETII-04), DPMJET and HIJING models are used to obtain the spectra. The results are compared with the measurements of STAR collaboration ob- tained at mid-rapidity of vertical bar y vertical bar < 0.5 in p(T) range of 0.3 < p(T) < 10 GeV/c. All models reproduce the ratios pi(-)/pi(+) and (p) over bar /p at low p(T) but could not predict well at high p(T). In addition, EPOS tunes and QGSJET tunes predict well the spectra of pi(+/-) meson and the ratios p/pi(+) and (p) over bar/pi(+) at low p(T). The HIJING and the QGSJET (tune I only) could reproduce all the spectra and all the ratios at a satisfactory level of precision and were found good among the models considered in the current study at RHIC energy.
