“…The energy deposited in the mid-rapidity kinematic range is controlled by the density of gluons contained in the colliding nuclei at moderately small values of the Bjorken scaling variable x [11]. At top RHIC collision energy the relevant range is x ≈ 10 −2 , while at the current LHC energy the value is x ≈ 10 −3 .…”

At the end of 2010, the CERN Large Hadron Collider started operation with heavy ion beams, colliding lead nuclei at a centre-of-mass energy of 2.76 TeV/nucleon and opening a new era in ultrarelativistic heavy ion physics at energies exceeding previous accelerators by more than an order of magnitude. This review summarizes the results from the first year of heavy ion physics at LHC obtained by the three experiments participating in the heavy ion program, ALICE, ATLAS, and CMS.

“…Experimental observation and theoretical analysis suggest that quark gluon plasma(QGP)-one of the colored phases of quantum chromodynamics(QCD) is formed in relativistic heavy ion collisions at top RHIC and LHC energies [1][2][3][4][5][6][7][8]. The temperature and density of QGP is much higher compared to the normal nuclear matter.…”

We study the chemical freeze-out dynamics of strange particles (K, Λ, Σ) from a homogeneous and isotropically expanding hadronic system of π, K, ρ, N, Λ and Σ with zero net baryon density. We use the momentum integrated Boltzmann equation and study their evolution over the bulk hadronic matter, a condition being similar to the one created at top RHIC and LHC energies. The cross-sections, which are input to the equations, are taken either from phenomenological models or parameterized by comparing against experimental data. From this microscopic calculation we find that these strange particles freeze-out near transition temperature ≈ Tc due to large relaxation time. The continuous cease of the inelastic processes due to gradual fall in the temperature and decrease in the number density, thus lead to early freeze out of strange hadrons K, Λ and Σ which happens sequentially near Tc. However, freeze-out of these strange species near Tc appears as a sudden and simultaneous process, which is mostly predicted by thermal model while explaining the yield of identified particles at RHIC and LHC energies.
