In this article, there are 18 sections discussing various current topics in the field of relativistic heavy-ion collisions and related phenomena, which will serve as a snapshot state art. Section 1 reviews experimental results some recent light-flavored particle production data from ALICE collaboration. Other mostly theoretical nature. Very strong but transient magnetic created could have important observational consequences. This has generated lot activity last decade. Sections 2, 7, 9, 10...
We present a detailed study of the variation shear viscosity $\ensuremath{\eta}$, with temperature and baryon chemical potential within framework Polyakov--Nambu--Jona-Lasinio model. $\ensuremath{\eta}$ is found to depend strongly on spectral width quasiparticles in The across phase diagram has distinctive features for different kinds transitions. These variations have been used possible location critical end point are cross-checked similar studies specific heat. Finally, using...
We discuss the 2+1 flavor Polyakov loop enhanced Nambu--Jona-Lasinio model in a finite volume. The main objective is to check volume scaling of thermodynamic observables for various temperatures and chemical potentials. observe possible violation with system size considerable window along whole transition region $T-\mu_q$ plane.
The Polyakov--Nambu--Jona-Lasinio model has been quite successful in describing various qualitative features of observables for strongly interacting matter, that are measurable heavy-ion collision experiments. question still remains on the quantitative uncertainties results. Such an estimation is possible only by contrasting these results with those obtained from first principles using lattice QCD framework. Recently a variety data were reported realistic continuum limit. Here we make...
Finite size consideration of matter significantly affects transport coefficients like shear viscosity, bulk electrical conductivity, which we have investigated here in the framework Polyakov--Nambu--Jona-Lasinio model. Owing to basic quantum mechanics, a nonzero lower momentum cutoff is implemented integrations used expressions constituent quark masses and coefficients. When system decreases, values these are enhanced low temperature range. At high domain, viscosity conductivity become...
The equation of state and fluctuations conserved charges in a strongly interacting medium under equilibrium conditions form the baseline upon which are built various possible scenarios relativistic heavy-ion collision experiments. Many these quantities have been obtained lattice QCD framework with reliable continuum extrapolations. Recently Polyakov--Nambu--Jona-Lasinio model has reparametrized to some extent reproduce quantitatively at vanishing chemical potentials. agreement was precise...

We have gone through a comparative study on two different kind of bulk viscosity expressions by using common dynamical model. The Polyakov-Nambu-Jona-Lasinio (PNJL) model in the realm mean-field approximation, including up to eight quark interactions for 2+1 flavor matter, is treated this dynamics. probed numerical equivalence as well discrepancy at vanishing chemical potential. Our estimation entropy density ratio follows decreasing trend with temperature, which observed most earlier...
Matter prevailing during the early stages of Universe or under extreme conditions in high-energy heavy-ion experiments supposedly possesses a rich phase structure. During evolution such system, complicated pictures transitions among various phases are studied as part hydrodynamics. This on most occasions, is considered to be non-viscous. However, theoretical studies reveal importance incorporating viscous effects into analysis. Here, paper discusses behavioral patterns transport coefficients...
Thermodynamic properties of strongly interacting matter are investigated using the Polyakov loop enhanced Nambu--Jona-Lasinio model along with some modifications to include hadrons. Various observables shown have a close agreement numerical data QCD on lattice. The advantage present scheme over similar study switching function is that here no extra parameters be fitted. As result can easily extended for finite chemical potentials.
We report the first model study of net charge fluctuations in terms D-measure within framework Polyakov-Nambu-Jona-Lasinio model. Net fluctuation is estimated from susceptibility evaluated using PNJL A parameterization freeze-out curve has been used to obtain D as a function sqrt(s). have discussed our results vis-a-vis recent experimental findings ALICE collaboration.
Properties of strongly interacting matter are quite well-described by the Polyakov loop enhanced Nambu-Jona—Lasinio (PNJL) model as it incorporates two important symmetries. However, discrepancies in low temperature domain remain unless hadronic effects entwined. Here we have tried to observe effect lowest lying hadrons i.e. ?-mesons (pions) considering their medium-dependent masses for zero chemical potential. The thermodynamic quantities now show satisfactory matches with existing lattice...
Keeping in the mind about Van der Walls gas equation, we have explore PV diagram of quark matter by using PNJL model and find a qualitative similarity.
