In this talk I discuss the modification of mesons in hot and dense QCD matter. After a brief review of changes of the spectral distribution of vector mesons, measured through dilepton-pair production in relativistic heavy-ion collisions, I present new results for the spectral functions of parity partners within the Functional Renormalization Group approach.

An excess of dileptons has been observed from the top RHIC energies of sqrt(s_NN)=200 GeV down to the lowest SPS energies of sqrt(s_NN)= 9 GeV. The RHIC beam energy scan and the new facilities under construction NICA and FAIR will allow to push the measurement of dileptons to much lower energies and to establish the onset of the low-mass excess related to chiral symmetry restoration and of the...

Direct photons, which are produced during all stages of a heavy-ion
collision, directly probe
the conditions of their production environment. The large yield and large
anisotropy of low
momentum direct photons observed in 200 GeV Au+Au collisions poses a
significant
challenge to theoretical models. Measurements at a lower collision energy
may provide
new insight on the origin of...

We compute the transport coefficients, namely, the coefficients of shear and bulk viscosity as
well as thermal conductivity for hot and dense matter within the Polyakov loop extended
Quark meson coupling model.
The estimation of the transport coefficients is made by solving the Boltzmann
kinetic equation in presence of mean fields of chiral as well as Polyakov loop within the relaxation...

Motivated by a strong, transient magnetic field that may affect the Quark-Gluon Plasma formed in off-central heavy-ion collisions, we present our recent progress on the computation of several key transport properties of the Quark-Gluon Plasma in the presence of magnetic field, in leading order of perturbative QCD that is applicable in high enough temperature.
These include the longitudinal...

Non-equilibrium corrections in a hot and dense QCD medium modify the ``hard thermal loops'' (HTL) which determine the resummed propagators for gluons with soft momenta as well as the Debye screening and Landau damping mass scales. We compute bulk viscous corrections to a thermal as well as to a non-thermal fixed point. The screening and damping mass scales are sensitive to the bulk pressure...

The impact of non-equilibrium effects on the dynamics of heavy-ion collisions is investigated by comparing a non-equilibrium transport approach, the Parton-Hadron-String-Dynamics (PHSD), to a 2D+1 viscous hydrodynamical model, which is based on the assumption of local equilibrium and conservation laws. Starting the hydrodynamical model from the same non-equilibrium initial condition as in the...

We address the issue of the deconfined phase transition from hadronic to partonic matter on microscopic basis.
We report about results from an extended dynamical
quasiparticle model (DQPM$^*$) in which the effective parton
propagators have a complex selfenergy that depends on the
temperature $T$ of the medium as well as on the chemical potential
$\mu_q$ and the parton three-momentum...

We use the gauge/gravity duality to model the out-of-equilibrium first stage of a heavy ion collision through the collision of gravitational shockwaves in numerical relativity. This investigation of collisions of sheets of energy density in a non-conformal theory with a gravity dual is the first non-conformal holographic simulation of a heavy ion collision. I will discuss the new physics that...

We study correlation functions of static quark antiquark pair in spatial separation in 2+1 flavor QCD in order to better understand the nature of color screening at high temperatures. We performed lattice calculations in a wide temperature range 140 MeV < T < 5.8 GeV using the highly improved staggered quark (HISQ) action and several lattice spacings to control discretization effects. From the...

At vanishing chemical potential the chiral phase transition in QCD with three degenerate quark flavors is expected to be of first order in the massless limit. As increasing the quark mass, a region of the first-order phase transition should terminate at a second-order critical endpoint before a crossover region appears. However, lattice studies with staggered-type quarks have shown that the...

We build effective models of the thermodynamics of QCD and match the couplings using a few measurements from the lattice. We discuss further predictions from the models, including corners where the lattice cannot reach yet.

The nature of chiral phase transition for QCD with two light quark flavors is not yet completely resolved. This is primarily because
one has to understand whether or not the anomalous U(1) symmetry in the flavor sector is effectively restored along with the chiral symmetry.
Since the physics near the chiral phase transition is essentially
non-perturbative, we employ first principles...

I will talk about the confinement and Chiral symmetry transitions from the perspective of an interacting ensemble of Instanton-dyons in SU(2) for two flavors. The confinement to deconfinement transition is seen as a transition from entropy dominated to energy dominated, due to the size of the Instanton-dyons being dependent on the Polyakov Loop. Towards higher temperatures the Polyakov loop...

We consider the implications for spatially inhomogenous phases,
and an associated Lifshitz point, in the phase diagram
of QCD. This could produce two critical endpoints in the plane
of T and $\mu$: a Lifshitz point at a higher $T$ and a smaller $\mu$ than for the "usual" critical endpoint (where the quartic scalar coupling vanishes).
The most dramatic signature of a spatially modulated...

The primary purpose of relativistic heavy–ion collisions at the Relativistic Heavy Ion Collider (RHIC) is to create QCD matter under high temperature and high density – Quark-Gluon Plasma (QGP), and study its properties. Due to their large masses, heavy quarks are produced on a short time scale in hard partonic scatterings during the early stages of the nucleus–nucleus collisions and the...

We study the effect of the missing resonances from the hadron spectrum on the extracted freezeout temperatures and chemical potentials from data on particle yields. We study several decay schemes for these missing resonances and estimate their influence in different freezeout schemes like 1CFO (unified freezeout of all hadrons), 1CFO+$\gamma_S$ ($\gamma_S$ accounting for undersaturation of...

We study the effects of expansion and viscous corrections on the hydrodynamical medium response to a high energy jet parton. More specifically, using a semi-analytical Gubser solution to relativistic fluid dynamics, modifications to the formed Mach cone, diffusive wake, and the momentum flow of the medium response along and perpendicular to the jet particle, are analyzed mode-by-mode. This...

Instanton dyons are topological objects generalizing instantons to the case of
nonzero VEV of the Polyakov line. Previous simulations of their ensembles
have reproduced the location and the order of the deconfinement transition in pure gauge theories. They also explain the location and crossover nature of the chiral transition in QCD with dynamical quarks. In the deformed QCD with nonzero...

The critical phenomena of strongly interacting matter are presented in the dual flux tube model at finite temperature. The phase transitions are considered in systems where the Critical Point (CP) is a distinct singular one existence of which is dictated by the dynamics of conformal symmetry breaking.

We study N=4 super Yang-Mills theory on the Coulomb branch (cSYM) in the strong coupling limit by using the AdS/CFT correspondence. The dual geometry is the rotating black 3-brane Type IIB supergravity solution with a single non-zero rotation parameter r_0 which sets a fixed mass scale corresponding to the scalar condensate <O>∼r^4_0 in the coulomb branch. We introduce a new ensemble where T...
