“…The extended lifetime enhances the rescattering effect. Figure 11(c) shows the energy dependence of the N (K * 0 )/N (K − ) ratio for minimum bias Au + Au and Cu + Cu [38] and 200 GeV [9]. At both energies, the N (K * 0 )/N (K − ) for p + p collisions is higher than the values in the heavy-ion collisions.…”

We report on K * 0 production at midrapidity in Au + Au and Cu + Cu collisions at √ s NN = 62.4 and 200GeV collected by the Solenoid Tracker at the Relativistic Heavy Ion Collider detector. The K * 0 is reconstructed via the hadronic decays K * 0 → K + π − and K * 0 → K − π + . Transverse momentum, p T , spectra are measured over a range of p T extending from 0.2 GeV/c up to 5 GeV/c. The center-of-mass energy and system size dependence of the rapidity density, dN/dy, and the average transverse momentum, p T , are presented. The measured N (K * 0 )/N (K) and N (φ)/N (K * 0 ) ratios favor the dominance of rescattering of decay daughters of K * 0 over the hadronic regeneration for the K * 0 production. In the intermediate p T region (2.0 < p T < 4.0 GeV/c), the elliptic flow parameter, v 2 , and the nuclear modification factor, R CP , agree with the expectations from the quark coalescence model of particle production.

The short-lived K(892)* resonance provides an efficient tool to probe properties of the hot and dense medium produced in relativistic heavy-ion collisions. We report measurements of K * in √ s NN = 200 GeV Au+Au and p + p collisions reconstructed via its hadronic decay channels K(892) * 0 → Kπ and K(892)using the STAR detector at the Relativistic Heavy Ion Collider at Brookhaven National Laboratory. The K * 0 mass has been studied as a function of p T in minimum bias p + p and central Au+Au collisions. The K * p T spectra for minimum bias p + p interactions and for Au+Au collisions in different centralities are presented. The K * /K yield ratios for all centralities in Au+Au collisions are found to be significantly lower than the ratio in minimum bias p + p collisions, indicating the importance of hadronic interactions between chemical and kinetic freeze-outs. A significant nonzero K * 0 elliptic flow (v 2 ) is observed in Au+Au collisions and is compared to the K 0 S and v 2 . The nuclear modification factor of K * at intermediate p T is similar to that of K 0 S but different from . This establishes a baryon-meson effect over a mass effect in the particle production at intermediate p T

“…The K * 0 /K and K * 0 /φ ratios from Au-Au collisions at √ s N N = 200 GeV correspond to 0-20% and 20-70% of the hadronic cross-section. The ratios are from measurements in e + e − collisions at 10.45 GeV[5], 29 GeV[6], 90 GeV[7] and 91 GeV[8] beam energies,pp at 5.6 GeV[9] and pp at 6.8 GeV[10], 19.7 GeV[11], 27.5 GeV[12], 52.5 GeV[13] and 63 GeV[14].The errors on the K * 0 /K and φ/K * 0 ratios at √ s N N = 200 GeV correspond to the quadratic sum of the statistical and systematic errors. The errors on the other ratios at √ s N N = 200 GeV are statistical only.…”
