摘要：
Applying a quark combination model for the hadronization of quark gluon plasma (QGP) and a relativistic transport (ART) model for the subsequent hadronic rescattering process, we investigate the production of K*(0) and Sigma* resonances in central Au + Au collisions at root s(NN) = 200 and 62.4 GeV. The initial K*(0) produced via hadronization is higher than the experimental data in the low-p(T) region and is close to the data at 2-3 GeV/c. We take into account the hadronic rescattering effects which lead to a strong suppression of K*(0) with low p(T) and find that the p(T) spectrum of K*(0) can be well described. The time span of the hadronic rescattering stage is estimated according to the suppressed magnitude of K*(0) yield. The p(T) spectrum of Sigma* directly obtained by quark combination hadronization in central Au + Au collisions at 200 GeV is in agreement with the experimental data, which shows a weak hadronic rescattering effects. The elliptic flow upsilon(2) of Sigma* in minimum-bias Au + Au collisions at 200 GeV and a p(T) spectrum of Sigma* at lower 62.4 GeV are predicted.
