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 an 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 mid-rapidity and compared it with the experimental data (CMS JHEP) and (CMS PAS) at LHC energy (Pb+Pb collisions, = TeV).

重离子碰撞中的状态方程和碳原子抑制

本文是我们在准粒子模型中抑制otto的后续工作，在这里我们以准胶子和准夸克/反夸克为状态方程，使用准粒子模型扩展了对charm态的研究。通过对重夸克电位进行热力学观测，即进行中等修饰。，压力，能量密度，声速等已被计算，其很好地适应与状态的用于胶子，无质量格子方程，以及大规模的调味血浆。为了获得热力学观测值，我们在准粒子图中使用了德拜质量。我们扩展了准粒子模型，以计算在扩展的，耗散性强相互作用的QGP介质（SIQGP）中的charm抑制。我们获得了关于快中速参与者数量的charm态抑制模式，并将其与LHC能量（Pb + Pb碰撞，= TeV）下的实验数据（CMS JHEP）和（CMS PAS）进行了比较。
