The production of the hadronic resonances K~(*0)(892),φ(1020),∑*(1385),and Ξ*(1530) in central AA collisions at(SNN)~(1/2)=17.3,200,and 2760 GeV is systematically studied.The direct production of these resonances at system hadronization is described by the quark combination model and the effects of hadron multiple-scattering stage are dealt with by a ultra-relativistic quantum molecular dynamics model(UrQMD).We study the contribution of these two production sources to final observation and compare the final spectra with the available experimental data.The p_T spectra of K~(*0)(892) calculated directly by quark combination model are explicitly higher than the data at low p_T■1.5 GeV,and taking into account the modification of rescattering effects,the resulting final spectra well agree with the data at all three collision energies.The rescattering effect on φ(1020) production is weak and including it can slightly improve our description at low p_T on the basis of overall agreement with the data.We also predict the p_T spectra of ∑*(1385) and Ξ*(1530),to be tested by the future experimental data.
The production of the hadronic resonances K ~ 0 * (892), φ (1020), Σ * (1385), and Ξ * (1530) in central AA collisions at (SNN) ~ (1/2) = 17.3, 200, and 2760 GeV is systematically studied. The direct production of these resonances at system hadronization is described by the quark combination model and the effects of hadron multiple-scattering stage are dealt with by a ultra-relativistic quantum molecular dynamics model (UrQMD). We study the contribution of these two production sources to final observation and compare the final spectra with the available experimental data. The p_T spectra of K ~ (* 0) (892) calculated directly by quark combination model are explicitly higher than the data at low p_T ■ 1.5 GeV, and taking into account the modification of rescattering effects, the resulting final spectra well agree with the data at all three collision energies. The rescattering effect on φ (1020) production is weak and including it can slightly improve our description at low p_T on the basis of overall agreement with the data. We also predict the p_T spectra of Σ * (1385) and Ξ * (1530), to be tested by the future experimental data.
