Abstract After discussing results of dilepton rates and electrical conductivity obtained from continuum extrapolated results of light quark correlation functions in quenched QCD I will give a review on recent developments in lattice QCD studies for quarkonia in the quark gluon plasma medium. Recent progress in the extraction of spectral properties from lattice QCD calculations of hadronic correlation functions will be discussed. Besides medium modifications of bound states and their… Expand

High Temperature QCD
I review recent results on QCD at high temperature on a lattice. Steady progress with staggered fermions and Wilson type fermions allow a quantitative description of hot QCD whose accuracy in manyExpand
Thermal dilepton rates from quenched lattice QCD
We present new lattice results on the continuum extrapolation of the vector current correlation function. Lattice calculations have been carried out in the deconfined phase at a temperature of T =Expand
Bottomonium from lattice QCD as a probe of the Quark-Gluon Plasma
We study the temperature dependence of bottomonium for temperatures in the range 0.4Te < T < 2.1Tc, using non-relativistic dynamics for the bottom quark and full relativistic lattice QCD simulationsExpand
Lorentz-boosted description of a heavy quarkonium
In this paper we study the relation between the light-front (infinite momentum) and rest-frame descriptions of quarkonia. While the former is more convenient for high-energy production, the latter isExpand
The Hot QCD White Paper: Exploring the Phases of QCD at RHIC and the LHC
The past decade has seen huge advances in experimental measurements made in heavy ion collisions at the Relativistic Heavy Ion Collider (RHIC) and more recently at the Large Hadron Collider (LHC).Expand
Charmonium dissociation and heavy quark transport in hot quenched lattice QCD
We study the properties of charmonium states at finite temperature in quenched lattice QCD on large and fine isotropic lattices. We perform a detailed analysis of charmonium correlation and spectralExpand
Momentum dependences of charmonium properties from lattice QCD
Abstract Charmonia produced in initial hard parton scatterings during heavy ion collisions move with respect to the medium rather than flow with the medium. Lattice studies suggest that charmoniumExpand
S wave bottomonium states moving in a quark-gluon plasma from lattice NRQCD

Charmonium propagation through a dense medium
Attenuation of a colourless ¯ cc dipole propagating with a large momentum through a hot medium originates from two sources, Debye screening (melting), and in- elastic collisions with surroundingExpand
Survival of charmonia in a hot environment
A colorless $\overline{c}c$ dipole emerging from a heavy ion collision and developing the charmonium wave function can be broken up by final state interactions (FSI) propagating through the hotExpand

Quarkonia and heavy-quark relaxation times in the quark-gluon plasma
A thermodynamic T-matrix approach for elastic two-body interactions is employed to calculate spectral functions of open and hidden heavy-quark systems in the quark-gluon plasma. This enables theExpand

Abstract Transport properties of a thermal medium determine how its conserved charge densities (for instance the electric charge, energy or momentum) evolve as a function of time and eventually relaxExpand

D(s) meson as a quantitative probe of diffusion and hadronization in nuclear collisions.
TLDR
The effects of diffusion in the hadronic phase are introduced and it is suggested that an increase of the D-meson elliptic flow compared to the D(s) can disentangle the transport properties of hadronic and QGP liquids. Expand
A way to estimate the heavy quark thermalization rate from the lattice
The thermalization rate of a heavy quark is related to its momentum diffusion coefficient. Starting from a Kubo relation and using the framework of the heavy quark effective theory, we argue that inExpand
