| 摘 要： | The rapidity densities at mid-rapidity and the transverse momentum distributions for strange hadrons produced in pp collisions are analyzed using the modi ed PACIAE model by considering the effect of inelastic (re)scattering processes ss→gg and gg→ss in parton (re)scattering. The calculated results of the transverse momentum spectra of the strangeness fitting with data measured by STAR and ALICE Collabora- tions can be improved, especially at large transverse momentum levels. This demonstrates that the effect of inelastic (re)scattering processes of ss→gg and gg→ss is not negligible at RHIC and LHC energy levels.
