“…T i represents the nuclear overlap function. The existing results on the R AA of φ [16] have been extended up to 21 GeV/c and measured in finer centrality bins, including in the 0-5% centrality interval, which is reported in the left panel of Fig.5. For the R AA , the reference spectrum is measured in pp collisions at √ s = 2.76 TeV, whereas for R pPb , shown in the right panel of Fig.5, the reference at √ s NN = 5.02 TeV has been obtained by interpolation of the measured cross sections at 2.76 and 7 TeV, by following the same approach used for charged particles described in [17].…”

Abstract. The production of hadronic resonances has been measured by the ALICE experiment at mid-rapidity in different collision systems (pp, p-Pb, and Pb-Pb). The measurements of K(892) * 0 and φ(1020) production in Pb-Pb collisions at √ s NN = 2.76 TeV and in pp at √ s = 2.76 and 7 TeV are complemented by the more recent measurement in p-Pb collisions at √ s NN = 5.02 TeV. The ratios of resonance to long lived hadron production in the three collision systems are compared in order to investigate re-scattering effects, which appear to be relevant for K * 0 in the most central Pb-Pb collisions, while φ behaves instead like a long-lived particle. Resonance observables contribute to draw the picture of central Pb-Pb collisions as a hydrodynamics-driven system. The comparison of the φ/p and p/π ratios as a function of transverse momentum (p T ) indicates that the mass of the particle determines the spectral shapes at low and intermediate p T in central Pb-Pb collisions. The mean transverse momentum, p T , of K * 0 and φ in central Pb-Pb collisions is consistent with that of the proton, which has similar mass. In pp and p-Pb collisions the p T of resonances does not follow mass ordering. The nuclear modification factors (R AA , R pA ) of the φ meson are also discussed in comparison with those of the stable hadrons.

We investigate the possibility of probing the hot and dense nuclear matter -created in relativistic heavy-ion collisions (HIC) -with strange vector mesons (K * ,K * ). Our analysis is based on the non-equilibrium Parton-Hadron-String Dynamics (PHSD) transport approach which incorporates partonic and hadronic degrees-of-freedom and describes the full dynamics of HIC on a microscopic level -starting from the primary nucleon-nucleon collisions to the formation of the strongly interacting Quark-Gluon-Plasma (QGP), followed by dynamical hadronization of (anti-)quarks as well as final hadronic elastic and inelastic interactions. This allows to study the K * andK * meson formation from the QGP as well as the in-medium effects related to the modification of their spectral properties during the propagation through the dense and hot hadronic environment in the expansion phase. We employ relativistic Breit-Wigner spectral functions for the K *
