We study the thermodynamics of hadronic matter using
the hadron resonance gas model with repulsive interactions
between baryons. The repulsive interactions are modeled
using the mean field approach. We study higher order fluctuations
of baryon number and strangeness within this approach and compare
the calculations with the most recent lattice results.
We find that the repulsive mean...

We construct an extension of the ideal hadron resonance gas (HRG) model which includes attractive and repulsive van der Waals (VDW) interactions between hadrons, and analyze different observables with this model [1]. The VDW parameters a and b are fixed by the ground state properties of nuclear matter, and this VDW-HRG model yields the nuclear liquid-gas transition at low temperatures and high...

The only first principle knowledge of the QCD equation of state at finite baryonic density is given from Lattice QCD as a Taylor expansion around $\mu_B = 0$. The coefficients of such an expansion are currently available up to order ${\cal O}(\mu_B^6)$. The expected critical behavior of QCD is in the same static universality class as the 3D Ising model. By means of a suitable parametrization...

Recently, an effective field theory for fluctuating dissipative hydrodynamics has been developed in 1511.03646 and 1701.07817. We apply this theory to investigate hydrodynamic fluctuations on the Bjorken expanding quark-gluon plasma (QGP). In particular, we explore effects due to nonlinear interactions among hydrodynamical variables and noises which are systematically incorporated in the...

We develop a set of kinetic equations for a correlator of thermal fluctuations which are equivalent to nonlinear hydro-dynamics with noise. We first show that the kinetic response precisely reproduces the one-loop renormalization of the shear viscosity for a static fluid previously discussed by Kovtun, Moore and Romatschke.
We then use the hydro-kinetic equations to analyze thermal...

Ever since the discovery of the quark-Gluon plasma (QGP) the location of the critical point in the QCD phase diagram - the end point of the first-order transition between hadron matter and QGP - has been a main research goal for heavy-ion collisions experiments. We use the gauge/gravity duality to study as first a four-dimensional, strongly-coupled gauge theory with a first-order thermal...

The experimental signatures of the QCD critical point rely on the universal singular behavior of the equation of state at the critical point. Therefore, we study singularities of the universal scaling equation of state of the phi4 theory, or the Ising model. We focus on
the relation between spinodal points that limit the domain of metastability for temperatures below the critical temperature,...

Correlations born before the onset of hydrodynamic flow can leave observable traces on the final state particles. Measurement of these correlations can yield important information on the isotropization and thermalization process. Starting with Israel-Stewart hydrodynamics and Boltzmann-like kinetic theory in the presence of dynamic Langevin noise, we derive a new partial differential equations...

Studies of charge-dependent azimuthal correlations for same- and opposite-sign particle pairs are presented in PbPb collisions at 5 TeV and pPb colisions at 5 and 8.16 TeV, with the CMS experiment at the LHC. The azimuthal correlations are evaluated with respect to the second- and also higher-order event planes, as a function of particle pseudorapidity and transverse momentum, and event...

We identify a new contribution to the chiral magnetic conductivity at finite frequencies-the magnetization current. This allows us to quantitatively reproduce the known field-theoretic time-dependent (AC) chiral magnetic response in terms of kinetic theory. We evaluate the corresponding AC chiral magnetic conductivity in two-flavor QCD plasma at weak coupling. The magnetization current results...

In heavy-ion collisions, an interesting question of phenomenological relevance is how the chiral imbalance generated at early times persists through a fluctuating background of sphalerons in addition to other ``non-anomalous” interactions with the QGP. To address this question, we construct a relativistic chiral kinetic theory using the world-line formulation of quantum field theory. This ...

The spin alignment of the φ-meson could be sensitive to different hadronization scenarios and the vorticity of the colliding system. We present the spin alignment measurements of φ-mesons produced at mid-rapidity with transverse momentum up to 5 GeV/c in STAR. The alignment is quantified by the diagonal spin density matrix elements ρ00 with respect to the normal of the 1st order event plane,...

HADES has a large acceptance combined with a good mass-resolution and good particle-identification capability, and is well equipped to study the azimuthal flow pattern not only for protons and charged pions, but also for lambdas, kaons, $\phi$-mesons and electrons-positron pairs, as well as deuterons, tritons and light nuclear fragments. With the statistics of seven billion Au-Au collisions...

Preliminary results for multiplicity, transverse momentum and forward energy fluctuations are presented for Be+Be and Ar+Sc collisions at 13A, 19A, 30A, 40A, 75A and 150A GeV/c beam momentum. The data were obtained by the NA61/SHINE detector at the CERN SPS. Centrality selection and forward energy measurement are based on the nucleon spectator energy in the forward hemisphere determined by the...

We show how the skewness and kurtosis of the proton number distribution are influenced by the fact, that some of the produced protons are bound in deuterons. Although the number of deuterons may not be high, the higher moments of proton multiplicity distribution are so sensitive to details that the effect is large. This is relevant for experimental studies of these moments which aim at...

The recent net-proton fluctuation results of the STAR experiment from the beam energy scan (BES) program at the BNL Relativistic Heavy Ion Collider (RHIC) have drawn much attention to explore the QCD critical point and the nature of the deconfinement phase transition.

It is well known that finite volume effects have marginal influence on the chiral condensate at zero temperature and chemical potential. However, in hot and dense medium, higher order cumulants of baryon number, including skewness and kurtosis, are expected to be more sensitive.
We explore the influence of finite volume effects on baryon number fluctuations in a non-perturbative chiral model....
