  Article: Constituent Quarks and Multi-strange Baryon Production in Heavy-Ion Collisions

  [show abstract] [hide abstract]
  ABSTRACT: In the frame work of the nuclear overlap model, we estimate the number of nucleon and quark participants in proton-proton, proton-nucleus and nucleus-nucleus collisions. We observe the nucleon normalized yield of multi-strange particles which show a linear rise with centrality, turns out to be a centrality independent scaling behavior when normalized to number of constituent quarks participating in the collision. This geometrical scaling indicates the partonic degrees of freedom playing important role in the production of multi-strange particles. Furthermore, we observe the constituent quark normalized yield when normalized to the strangeness content, it shows a strangeness independent scaling behavior. We give a comparison of data with HIJING, AMPT and UrQMD models to understand the particle production dynamics.

  Article: Probing the QGP Phase Boundary with Thermal Properties of $\phi$ Mesons

  Raghunath Sahoo, Tapan K. Nayak, Jan-e Alam, Basanta K. Nandi, Sonja Kabana
  [show abstract] [hide abstract]
  ABSTRACT: A novel attempt has been made to probe the QCD phase boundary by using the experimental data for transverse momenta of {\phi} mesons produced in nuclear collisions at AGS, SPS and RHIC energies. The data are confronted with simple thermodynamic expectations and lattice QCD results. The experimental data indicate a first-order phase transition, with a mixed phase stretching the energy density between \sim1 and 3.2 GeV/fm3 corresponding to SPS energies.

  Article: $\phi$ Meson As a Probe of QCD Equation of State

  Raghunath Sahoo, Tapan K. Nayak, Jan-e Alam, Sonia Kabana, Basanta K. Nandi, Durga P. Mahapatra
  [show abstract] [hide abstract]
  ABSTRACT: In this work, we extract the QCD Equation of State (EoS) using experimental results of the $\phi$ meson produced in nuclear collisions at AGS, SPS and RHIC energies. The data are confronted to simple thermodynamic expectations and lattice results. The experimental data indicate a first order phase transition, with a mixed phase stretching energy density between $\sim$ 1 and 3.2 GeV/$fm^3$.

  Article: Indication of a coexisting phase of quarks and hadrons in nucleus-nucleus collisions

  Bedangadas Mohanty, Jan-e Alam, Sourav Sarkar, Tapan K. Nayak, Basanta K. Nandi
  [show abstract] [hide abstract]
  ABSTRACT: The variation of average transverse mass of identified hadrons with charge multiplicity has been studied for AGS, SPS, and RHIC energies. The observation of a plateau in the average transverse mass for multiplicities corresponding to SPS energies is attributed to the formation of a coexistence phase of quark gluon plasma and hadrons. A subsequent rise for RHIC energies may indicate a deconfined phase in the initial state. Several possibilities which can affect the average transverse mass are discussed. Constraints on the initial temperature and thermalization time have been put from the various experimental data available at SPS energies.
