Role of event multiplicity on hadronic phase lifetime and QCD phase boundary in ultrarelativistic collisions at energies available at the BNL Relativistic Heavy Ion Collider and CERN Large Hadron Collider

Hadronic resonances, having very short lifetime, like K * 0 , can act as useful probes to understand and estimate lifetime of hadronic phase in ultra-relativistic proton-proton, p-Pb and heavy-ion collisions. Resonances with relatively longer lifetime, like φ meson, can serve as a tool to locate the QGP phase boundary. We estimate a lower limit of hadronic phase lifetime in Cu-Cu and Au-Au collisions at RHIC, and in pp, p-Pb and Pb-Pb collisions at different LHC collision energies. Also, we obtain the effective temperature of φ meson using Boltzmann-Gibbs Blast-Wave function, which gives an insight to locate the QGP phase boundary. We observe that the hadronic phase lifetime strongly depends on final state charged-particle multiplicity, whereas the QGP phase and hence the QCD phase boundary shows a very weak multiplicity dependence. This suggests that the hadronisation from a QGP state starts at a similar temperature irrespective of charged-particle multiplicity, collision system and collision energy, while the endurance of hadronic phase is strongly dependent on final state charge-particle multiplicity. PACS numbers: 25.75.Dw,14.40.Pq * Corresponding Author Email: Raghunath.Sahoo@cern.ch servations of QGP-like properties such as strangeness enhancement [4], double-ridge structure [5] etc. in smaller collision systems like pp and p-Pb collisions are note worthy. These developments have important consequences on the results obtained from heavy-ion collisions, as pp collisions are used as baseline measurements while characterizing the medium properties in heavy-ion collisions.A closer look at the LHC pp collisions, especially the high-multiplicity events is a call of time.

“…In practice, it also possible to test, if the Gaussian approximation (to the rapidity distribution, dN/dy ) is satisfactory or not, by fitting (the pseudorapidity distribution, dN/dη p ) using Eqs. (24), (25), (42) and (43). If such a fit turned out to be not satisfactory for a given dataset and a given experimental precision, one can attempt an improved fit using the more precise Eq.…”

We discuss a recently found family of exact and analytic, finite and accelerating, 1+1 dimensional solutions of perfect fluid relativistic hydrodynamics to describe the pseudorapidity densities and longitudinal HBT-radii and to estimate the lifetime parameter and the initial energy density of the expanding fireball in Au+Au collisions at RHIC with √ s N N = 130 GeV and 200 GeV colliding energies. From these exact solutions of relativistic hydrodynamics, we derive a simple and powerful formula to describe the pseudorapidity density distributions in high energy proton-proton and heavy ion collisions, and derive the scaling of the longitudinal HBT radius parameter as a function of the pseudorapidity density. We improve upon several oversimplifications in Bjorken's famous initial energy density estimate, and apply our results to estimate the initial energy densities of high energy reactions with data-driven pseudorapidity distributions. When compared to similar estimates at the LHC energies, our results indicate a surprising and non-monotonic dependence of the initial energy density on the energy of heavy ion collisions.

“…The red solid lines show the results obtained when we apply our core-corona separation using the two different values of the density cutoff parameter (triangles: ρ q = 4ρ q0 , circles: ρ q = 5ρ q0 ). The model results are compared to data from different experiments [79][80][81][82][83][84][85][86], which are shown as blue square symbols.…”

Core-corona separation in the UrQMD hybrid model

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
