We calculate ratios of up to $4^{th}$ order cumulants of net baryon number
fluctuations in (2+1)-flavor QCD using
next-to-leading order Taylor expansions in terms of temperature and the
the baryon number, strangeness, and electric charge chemical potentials.
We establish relations between these cumulant ratios, which hold at
small values of the chemical potentials. These QCD results are...

Fluctuations and correlations of conserved quantities (baryon number, strangeness, and charge) can be used to probe phases of strongly interacting QCD matter and the possible existence of a critical point in the phase diagram. The cumulants of the multiplicity distributions related to these conserved quantities are expected to be sensitive to possible increased fluctuations near a critical...

HADES is a multi-purpose charged-particle detector operated at the SIS18 synchrotron located at the GSI Helmholtz Center for Heavy Ion Research in Darmstadt, Germany. The provided ion beam energies of 1-2 A GeV are the lowest of all currently running heavy-ion experiments and result in the highest baryo-chemical potentials at freeze-out in case of Au+Au collisions. With the high statistics of...

One of the main physics goals of the NA61/SHINE programme on strong interactions is the study of the properties of the onset of deconfinement. This goal is pursued by performing an energy (beam momentum 13A - 158A~GeV/c) and system size (p+p, p+Pb, Be+Be, Ar+Sc, Xe+La) scan.
This talk reviews results and plans of NA61/SHINE.
In particular, recent inclusive spectra in inelastic p+p and...

The event-by-event fluctuations of conserved quantities within a fixed rapidity range in ultrarelativistic nucleus-nucleus collisions give information about the state of matter created in these collisions as well as the phase diagram of nuclear matter. We will present the latest results from ALICE on net-proton fluctuations, which are closely related to net-baryon number fluctuations. ...

At zero baryon density lattice QCD is an established tool, that provides precise theoretical results. Calculations at non zero densities however require new techniques to deal with the sign problem. In this talk I will review the recent progress that is made in lattice QCD to investigate QCD at non-vanishing baryon chemical potential.

As the density of matter increases, atomic nuclei disintegrate into nucleons and, eventually, the nucleons themselves disintegrate into quarks. The phase transitions (PTs) between these phases can vary from steep first order phase transitions to smooth crossovers, depending on certain conditions. First order phase transitions with more than one globally conserved charge, so-called...

A goal of the research at the Relativistic Heavy Ion Collider (RHIC) is to explore deconfined quark-gluon matter. Directed flow ($v_{1}$) is one observable that is sensitive to the dynamics of the system at early times of the collisions. Model calculations have indicated that the $v_{1}$-slope ($dv_1/dy$) at mid-rapidity is sensitive to the Equation of State (EoS) of the system. STAR has...

Measurements of the beam energy dependence of anisotropic flow can provide crucial insight on the baryon chemical potential ($\mu_B$) and temperature ($T$) dependences of viscous damping and its associated specific shear viscosity $\eta/s$ in QCD matter. It has been predicted that the $\mu_B$ and $T$ dependence of $\eta/s$ could be sensitive to the critical endpoint (CEP) in the phase...

We present the latest results on the collision energy dependence of eta/s, obtained from a Bayesian model-to-data analysis of UrQMD + viscous hydrodynamics hybrid model [1] to RHIC beam energy scan data for Au+Au collisions at 19.6, 39 and 62.4 GeV. A change in eta/s over beam energy scan range would suggest that, in addition to temperature, eta/s depends also on baryon chemical potential...

The search for the QCD critical point in heavy-ion collision experiments requires dynamical modeling of the bulk evolution of the QCD matter as well as of the fluctuations near the critical point. We develop a general formalism which couples hydrodynamics of a relativistic fluid to critical fluctuations. The resulting “Hydro+” theory extends hydrodynamics into the regime where the critical...

Chiral Magnetic Effect (CME) is the macroscopic manifestation of the fundamental chiral anomaly in a many-body system of chiral fermions, and emerges as anomalous transport current in hydrodynamic framework.

We present a first-principle study of anomaly induced transport phenomena based on real-time lattice simulations with dynamical fermions coupled simultaneously to non-Abelian $SU(Nc)$ and Abelian $U(1)$ gauge fields.

The chiral magnetic effect (CME) is a macroscopic manifestation of the quantum anomaly.

Non-central heavy-ion collisions have large ($\sim 10^{3} \hbar$ in the BES) angular momentum which may be transferred, in part, to the quark-gluon plasma through shear forces that generate a vortical substructure in the hydrodynamic flow field. The vortical nature of the system is expected to polarize emitted hadrons along the direction of system angular momentum. $\Lambda$ and...

We study the structure of vorticity and hydrodynamic helicity fields in peripheral heavy ion collisions using the kinetic Quark-Gluon String and Hadron-String Dynamics models. We observe the formation of specific toroidal structures of vorticity field (vortex sheets). Their existence is mirrored in the polarization of hyperons of the percent order. Its rapid decrease with energy was predicted...

A pair-normalized two-particle covariance versus the rapidity of
the two particles, called R$_2$, was originally studied [1] in
ISR and FNAL data in the 1970's and has recently seen renewed

longitudinal direction. These rapidity correlations can be
decomposed onto a basis set of Legendre polynomials with
prefactors,...

Building on an analysis of hydrodynamic long time tails for a Bjorken expansion (Akamatsu 2016), we discuss the hydrodynamic scales associated with transiting the critical point.

The goal of the Fixed-Target Program at STAR (FXT) is to extend BES-II to energies below 7 GeV and to baryon chemical potentials, μB, up to about 720 MeV. Studying these lower energy collisions could clarify the behavior of several observables studied during BES-I that suggest a transition from a parton-dominated regime to a hadron-dominated regime.

In order to explore phase structures in high-baryon density regime of the QCD phase diagram and to study dense quark/hadronic matter which may exist in the core of neutron stars, we proposed a heavy-ion program at J-PARC (J-PARC-HI). In heavy-ion collisions at J-PARC (1-19 AGeV/c), the maximum baryon density will reach 5-10 times the normal nuclear density.
We designed a heavy-ion...
