“…This is strongly delivered that QGP may lie in the non-perturbative domain of the Quantum-Chromodynamics which is very tough to address the both 2 analytically and computationally. Similar findings related to the quark-gluon plasma were explored in the recent lattice studies, which predicted the EoS of the interacting quark gluon plasma even at T ∼ 4Tc [22][23][24][25].…”

Charmonium Suppression in an Anisotropic Hot Qcd Medium Using Quasi-Particle Model

We have studied the properties of charmonium states through the in- medium modifications to both perturbative and non-perturbative term using the Cornell potential. The flavor dependence of the binding energies of the heavy quarkonia states in isotropic as well as anisotropic case have been obtained by employing the quasi-particle Debye mass with baryonic chemical potential at fixed value of μb =300MeV, which is computed by employing the quasi-particle picture. There is significant comparision has been made for the variation of binding energy using different Debye masses, such as quasi-particle Debye mass, leading order Debye mass, and quasi-particle Debye mass with baryonic chemical potential in isotropic and as well as anisotropic case. Further, we observe that the dissociation temperatures of anisotropic medium are higher than the isotropic medium using quasi-particle picture in full QCD case. By using these dissociation temperatures as an input, we explore the sensitivity of prompt and sequential suppression at LHC (1).

“…This strongly suggest that QGP may lie in the non-perturbative domain of QCD which is very hard to address both analytically and computationally. Similar conclusion about QGP and perfect fludity of QGP have been reached from recent lattice studies and from the AdS/CFT studies [18], spectral functions and transport coefficients in lattice QCD [19] and studies based on classical strongly coupled plasmas [20,21], which predict that the equation of state (EoS) is interacting even at T ∼ 4T c [22][23][24][25].…”

The present article is the follow-up of our work Bottomonium suppression in quasi-particle model, where we have extended the study for charmonium states using quasi-particle model in terms of quasi-gluons and quasi quarks/antiquarks as a equation of state. By employing medium modification to a heavy quark potential thermodynamic observables viz. pressure, energy density, speed of sound etc. have been calculated which nicely fit with the lattice equation of state for gluon, massless and as well massive flavored plasma. For obtaining the thermodynamic observables we employed the debye mass in the quasi particle picture. We extended the quasi-particle model to calculate charmonium suppression in an expanding, dissipative strongly interacting QGP medium (SIQGP). We obtained the suppression pattern for charmonium states with respect to the number of participants at midrapidity and compared it with the experimental data (CMS JHEP) and (CMS PAS) at LHC energy (Pb+Pb collisions, √ sNN = 2.76 TeV).

This non-technical review article is aimed at readers with some physics background, including beginning research students. It provides a panoramic view of the main theoretical developments in high energy physics since its inception more than half a century ago, a period in which experiments have spanned an enormous range of energies, theories have been developed leading up to the Standard Model, and proposals -- including the radical paradigm of String Theory -- have been made to go beyond the Standard Model. The list of references provided here is not intended to properly credit all original work but rather to supply the reader with a few pointers to the literature, specifically highlighting work done by Indian authors.Comment: 52 pages, 14 figures, corrected versio

Present status of lattice QCD at nonzero T and μ

Abstract: I review a few selected topics in lattice quantum chromodynamics, focusing more on the recent results. These include (i) the equation of state and speed of sound, (ii) J/ψ suppression, (iii) flavour correlations and (iv) the QCD phase diagram in the µ-T plane.
