NA61/SHINE is a fixed target experiment at the CERN Super Proton Synchrotron. The main goals of the experiment are to discover the critical point of strongly interacting matter and to study the properties of the onset of deconfinement.
In order to reach these goals, a study of hadron production properties is performed in nucleus-nucleus, proton-proton and proton-nucleus interactions as a...

Over the last three decades, proton-proton (pp) collisions have successfully provided a reference sample for the study of nucleus-nucleus collisions and have helped to unveil features attributed there to QGP formation. The results from the LHC pp program show some intriguing trends where the pp collisions resemble those of nucleus-nucleus collisions and therefore bring into question the...

One of the most significant aspects of QCD thermodynamics is understanding how the transition from hadrons to their constituents—quarks and gluons—relates to the underlying deconfinement and chiral
dynamics. This is of major relevance for heavy-ion collisions, as well as in the study of cold and dense systems, such as compact stars. The latter, however, is often studied exclusively in models...

We study the phase diagram of two-flavor massless QCD at finite baryon density
by applying the functional renormalization group (FRG) for a quark-meson model with σ, π,and ω mesons. The dynamical fluctuations of quarks, σ, and π are included into the flow equations,while the amplitudes of ω-fields are also allowed to fluctuate. At high temperature the effects of the ω-field on the phase...

In this talk I will summarize our recent efforts to determine the location of the
critical end point within the framework of Dyson-Schwinger equations. We work
in an approximation that reproduces lattice results for the temperature dependent condensate and the unquenched gluon propagator at zero chemical potential.
I discuss results for the phase diagram with 2+1 and 2+1+1 quark flavours...

To understand the mechanism of confinement in QCD (and QCD-like theories) remains a great challenge. In the past decade an interesting new approach to this problem has emerged by studying the confinement mechanism from ``above''. That is, one could probe how confinement occurs by first studying the finite temperature plasma phase above but close to the confinement transition temperature Tc. ...

Paradigm shift in gauge topology at finite temperatures, from the instantons to their constituents
-- instanton-dyons -- has recently lead to studies of their ensembles and very significant advances.
Like instantons, they have fermionic zero modes, and their collectivization
at sufficiently high density explains the chiral symmetry breaking.
Unlike instantons, these objects have ...

The holographic connection between strongly-coupled gauge theories and extra-dimensional gravitational theories has succeeded in describing many features of non-perturbative QCD. Phenomenological models called AdS/QCD use a five-dimensional AdS black hole to study thermodynamic properties of the quark-gluon plasma. In this talk, we focus on the phase transition that occurs as chiral symmetry...

We propose a new way to correct for finite centrality bin width effect i.e. participant fluctuations in high energy nucleus-nucleus collisions. The MMCP method allows to separate participant fluctuations and obtain fluctuations from one participant - a source - from a combination of the experimentally measured first four moments. The EPOS model is used for the numerical check of the MMCP for...

During the first phase of the beam energy scan (BES-I), the STAR collaboration investigated observables as a function beam energy in order to map the QCD phase diagram.
Some of these observable showed hints of non-monotonic behavior, but limited statistics, analysis dependent collision centrality estimation, and poor event plane resolution did not allow firm conclusions for...

The NA61/SHINE experiment aims to discover the critical point of strongly interacting matter and study the properties of the onset of deconfinement. These goals are to be achieved by performing a two dimensional phase diagram (T-mu_B) scan by measurements of hadron production properties in proton-proton, proton-nucleus and nucleus-nucleus interactions as a function of collision energy and...

Adding gradient terms to thermodynamic quantities has long been a means to incorporate finite-range interactions into descriptions of equilibrated physics. Here, we show how gradient terms can be incorporated into hydrodynamic treatments, thus making it possible to dynamically model the growth of fluctuations and correlations of charge, energy and momentum in a consistent fashion for any...

Based on phenomenological construction of QCD equations of state for the neutron structure, we extend the framework to finite temperature equations of state which have direct relevance to neutron star mergers and supernovae. Our primary target is a matter at baryon density of 5-10n0 (n0: nuclear saturation density) and temperature of ~10-100 MeV in which quark matter may be important. Using a...

The effective models of QCD, like NJL or PNJL model describe properties of
hadron matter using mean field approximation. At that time at critical
region quark-meson correlations can play crushing role. We consider
\Phi-derivable approximation as an instrument for description of matter at
finite temperature and density. Such approach treats interactions in terms
of fully-dressed...

The motivations of this program include looking for the turn-off of signatures of the Quark-Gluon plasma (QGP), searching for the possible QCD critical point and studying the nature of the phase transition between hadronic and partonic matter.

Common lore suggests that no well-dened order parameters exist in N-color QCD with massive quarks which are non-trivial at zero baryon density. However we find that, such order parameters do exist when there are n_f quark flavors with a common mass and gcd(nf ;N) > 1. Such theories have Zd color-flavor center symmetry arising from intertwined color-center transformations and cyclic flavor...

We use a semiclassical method to analyze the phase structure of SU(N) gauge theory at infinite N in the presence of the external field. The effective potential can be written in terms of a Landau free energy for Polyakov loops, and we construct it using the perturbative contribution and a double trace deformation as the unknown confining potential. We show that there is a surface of a...

We use the linear sigma model coupled to quarks to compute the effective potential beyond the mean field approximation, including the contribution of the ring diagrams at finite temperature and baryon density and the thermal corrections of the coupling constants. This effective potential is then used to study the fluctuations of the order parameter v. In this work, we specifically localize the...
