“…The new preliminary PHENIX results substantially increase the p T range of the measurements up to 7 GeV/c by not requiring particle identification for one or both K-meson. In the overlapping p T range the new measurements are consistent with the published PHENIX results [33,34] in which particle identification of both daughter particles was required. One should note that the new measurements done by PHENIX did not resolve the problem of the difference in the particle yields measured by STAR and PHENIX collaborations.…”

This article reviews the current status of experimental results obtained in the measurement of light vector mesons produced in proton-proton and heavy ion collisions at different energies. The review is focused on two phenomena related to the light vector mesons; the modification of the spectral shape in search of chiral symmetry restoration and suppression of the meson production in heavy ion collisions. The experimental results show that the spectral shape of light vector mesons are modified compared to the parameters measured in vacuum. The nature and the magnitude of the modification depends on the energy density of the media in which they are produced. The suppression patterns of light vector mesons are different from the measurements of other mesons and baryons. The mechanisms responsible for the suppression of the mesons are not yet understood. Systematic comparison of existing experimental results points to the missing data which may help to resolve the problem.

“…Closed stars (red online) are the STAR results measured in the centrality bins coinciding with PHENIX, for open stars (blue online) the centrality bins are different. The data is taken from [26,[33][34][35] collisions is higher. It also results in a higher integrated φ-meson yields since the slopes of the spectral lines agree.…”

“…2. As compared to the previously reported Au+Au results [8] obtained with the "two kaons PID" approach, the new "no PID" analysis extends the range of the measurements to higher p T up to 7 GeV/c. In turn, the new "one kaon PID" analysis of p+p data extends the range of the "no PID" measurements reported in [9] to lower p T down to 0.9 GeV/c.…”

“…φ mesons are as heavy as protons but data from RHIC now impressively confirm that the elliptic flow and nuclear modification factor are very similar to those for kaons [14]. We can now be very sure that the meson vs baryon signature at intermediate P T is very robust and can neither be explained by an extrapolation of hydrodynamics nor by perturbative jet production and fragmentation.…”
