The measurement of resonance production in ultrarelativistic heavy-ion collisions provides a glimpse of the hadronic medium properties and its evolution at different stages. Resonances decaying into hadrons are used to estimate the time span and hadronic interaction cross section in the hadronic phase between chemical and kinetic freeze-out. Specifically, the comparison of K*0(892) and ϕ(1020) resonances is interesting as the lifetimes of these particles differ by about a factor of 10. Moreover, the nuclear modification factor and azimuthal anisotropy measurements of mesonic resonances, which measure parton energy loss in medium and reflect partonic collectivity, can also probe particle-species and mass ordering.
The K*0(892) and ϕ(1020) resonance production at mid-rapidity (|y| <0.5), measured in high energy (Au+Au, Cu+Cu, d+Au and p + p) collisions at RHIC with the STAR experiment, reconstructed by their hadronic decay in Kπ and KK, respectively, are discussed. Mesons’ spectra, yields, mean transverse momentum 〈pT〉, nuclear modification factor, and azimuthal anisotropy are discussed as a function of centrality and collision energy.
