“…In addition, if production is dominantly from coalescence, one expects the width of the rapidity distribution of mesons to be related to those for charged kaons as 1/ 2 = 1/ 2 − + 1/ 2 + . Measurements at SPS energies show a clear deviation of the data from the above expectation [55]. Finally, if production is dominantly from coalescence it would be reflected in elliptic flow (V 2 ) measurements.…”

The main aim of the relativistic heavy-ion experiment is to create extremely hot and dense matter and study the QCD phase structure. With this motivation, experimental program started in the early 1990s at the Brookhaven Alternating Gradient Synchrotron (AGS) and the CERN Super Proton Synchrotron (SPS) followed by Relativistic Heavy Ion Collider (RHIC) at Brookhaven and recently at Large Hadron Collider (LHC) at CERN. These experiments allowed us to study the QCD matter from center-of-mass energies (sNN) 4.75 GeV to 2.76 TeV. Theϕmeson, due to its unique properties, is considered as a good probe to study the QCD matter created in relativistic collisions. In this paper we present a review on the measurements ofϕmeson production in heavy-ion experiments. Mainly, we discuss the energy dependence ofϕmeson invariant yield and the production mechanism, strangeness enhancement, parton energy loss, and partonic collectivity in nucleus-nucleus collisions. Effect of later stage hadronic rescattering on elliptic flow (v2) of proton is also discussed relative to corresponding effect onϕmesonv2.

“…The K − /π − ratio scales with dN ch /dη at both energies and there is no hint of an additional strangeness enhancement of charged kaons in the smaller Cu + Cu system compared to the larger Au + Au system. Early works from Super Proton Synchrotron (SPS) energies reported such additional relative strangeness enhancement in the K/π ratio for smaller systems, although no final confirmation of this observation is available [17,18]. The pion and kaon enhancement factors are compared in Fig.…”

Identified charged pion, kaon, and proton spectra are used to explore the system size dependence of bulk freezeout properties in Cu + Cu collisions at √ s NN = 200 and 62.4 GeV. The data are studied with hydrodynamically motivated blast-wave and statistical model frameworks in order to characterize the freeze-out properties of the system. The dependence of freeze-out parameters on beam energy and collision centrality is discussed. Using the existing results from Au + Au and pp collisions, the dependence of freeze-out parameters on the system size is also explored. This multidimensional systematic study furthers our understanding of the QCD phase diagram revealing the importance of the initial geometrical overlap of the colliding ions. The analysis of Cu + Cu collisions expands the system size dependence studies from Au + Au data with detailed measurements in the smaller system. The systematic trends of the bulk freeze-out properties of charged particles is studied with respect to the total charged particle multiplicity at midrapidity, exploring the influence of initial state effects.

“…In the last part of this paper, we will discuss the results on the centrality dependence of different hadronic observables and compare them to data [79,[90][91][92][93] (the centrality selection with regard to the number of wounded nucleons is taken from [94]). Figure 9 displays the midrapidity (|y| < 0.5) yields of pions and 's divided by the number of wounded nucleons as a function of N W .…”

We employ the UrQMD transport + hydrodynamics hybrid model to estimate the effects of a separation of the hot equilibrated core and the dilute corona created in high energy heavy ion collisions. It is shown that the fraction of the system which can be regarded as an equilibrated fireball changes over a wide range of energies. This has an impact especially on strange particle abundancies. We show that such a core corona separation allows to improve the description of strange particle ratios and flow as a function of beam energy as well as strange particle yields as a function of centrality.Comment: 10 pages, 11 figures, version accepted by PR
