The direct production of these resonances at system hadronization are 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 $K^{*}(892)$ calculated directly by quark combination model are explicitly higher than the data at low $p_T \\lesssim 1.5$ 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 $\\phi(1020)$ 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 $\\Sigma^{*}(1385)$ and $\\Xi^{*}(1530)$ to be tested by the future experimental data.", "revisions": [ { "version": "v1", "updated": "2016-08-12T04:45:02.000Z" } ], "analyses": { "keywords": [ "relativistic heavy ion collisions", "resonance production", "energy dependence", "quark combination model", "ultra-relativistic quantum molecular dynamics model" ], "note": { "typesetting": "TeX", "pages": 5, "language": "en", "license": "arXiv", "status": "editable" } } }
