“…[26] and compare our calculations with the LQCD results of Ref. [16]. The temperature dependence of pressure and energy-density of hadron gas for infinite as well as for a few representative finite sizes, R = 2.5, 3 and 5 fm, for different options, 1) Ideal HRG, 2) Ideal HRG + Hagedorn States and 3) Ideal HRG + Hagedorn States + EV effect are presented in Figures 1 and 2, respectively.…”

“…The hadronic phase of the QCD medium is successfully addressed also by the Hadron Resonance Gas (HRG) Model [10][11][12], in statistical thermodynamic framework. An ideal HRG, formulated with discrete mass spectrum of * Electronic address: prem@vecc.gov.in identified hadrons and resonances, has been reinforced with the ab-initio confirmation [13][14][15][16] from the LQCD. Also, as yet unmeasured higher-mass hadron states, provided by the exponentially growing continuum mass spectrum, proposed [17] by R. Hagedorn, have important contribution to the equation of state (EoS) [18][19][20] below the critical temperature (T c ) for the QCD change of phase.…”

We study the system-size dependence of Knudsen number, a measure of degree of thermalization, for hadron resonance gas that follows the Lattice-QCD equation of state at zero chemical potential. A comparison between Knudsen numbers for the AuAu collisions at RHIC and the hadron gas of size similar to the size of high-multiplicity pp events at LHC, reassures the applicability of hydrodynamics in interpreting the features of particle production in high-multiplicity pp events.

“…We further consider the lattice QCD EoS [74] in terms of its quasi-particle description, we denote it as LEoS. Although there are more recent lattice results with improved lattice actions and more refined lattice [75,76], but to update the current model requires pure glue results for the trace anomaly with the same lattice set-up. Therefore, such attempts are beyond the scope of the present work.…”

Dissociation of heavy quarkonium in hot QCD medium in a quasiparticle model

et al. 2016

Following a recent work on the effective description of the equations of state for hot QCD obtained from a Hard thermal loop expression for the gluon self-energy, in terms of the quasi-gluons and quasiquark/anti-quarks with respective effective fugacities, the dissociation process of heavy quarkonium in hot QCD medium has been investigated. This has been done by investigating the medium modification to a heavy quark potential. The medium modified potential has a quite different form (a long range Coulomb tail in addition to the usual Yukawa term) in contrast to the usual picture of Debye screening. The flavor dependence of the binding energies of the heavy quarkonia states and the dissociation temperature have been obtained by employing the debye mass for pure gluonic and full QCD case computed employing the quasi-particle picture. Thus estimated dissociation patterns of the charmonium and bottomonium states, considering Debye mass from different approaches in pure gluonic case and full QCD, have shown good agreement with the other potential model studies. 24.85.+p; 12.38.Mh PACS

We determine the contribution to the anomalous magnetic moment of the muon from the α 2 QED hadronic vacuum polarization diagram using full lattice QCD and including u/d quarks with physical masses for the first time. We use gluon field configurations that include u, d, s and c quarks in the sea at multiple values of the lattice spacing, multiple u/d masses and multiple volumes that allow us to include an analysis of finite-volume effects. We obtain a result for a HVP,LO µ of 667(6)(12) × 10 −10 , where the first error is from the lattice calculation and the second includes systematic errors from missing QED and isospin-breaking effects and from quark-line disconnected diagrams. Our result implies a discrepancy between the experimental determination of aµ and the Standard Model of 3σ.
