The ATLAS collaboration has analyzed event-to-event fluctuations of the transverse momentum per particle as a function of the particle multiplicity. In the most central collisions, the variance of fluctuations decreases steeply. I show that this can be explained simply, provided that one takes into account two combined effects: First, for a fixed collision multiplicity, the impact parameter...
The hydrodynamic flow-like behavior of charged hadrons in high-energy lead-lead collisions is studied through their multiparticle correlations. The elliptic anisotropy harmonic values based on different orders of multiparticle cumulants, v2{2k}, are measured up to the tenth order (k = 5) as functions of the collision centrality at a nucleon-nucleon center-of-mass energy of 5.02 TeV. The data...
The azimuthal anisotropy of the observed distribution of hadrons results from the anisotropy of the initial conditions. A more detailed picture is in principle provided by correlations of the flow coefficients in various kinematic regions. This includes the decorrelation of flow anisotropy in rapidity, the correlation of the anisotropy with mean pt, or the decorrelation of the anisotropy in...
Recent developments on a deep learning feed-forward network for estimating elliptic flow (v2) coefficients in heavy-ion collisions have shown us the prediction power of this technique. The success of the model is mainly the estimation of v2 from final state particle kinematic information and learning the centrality and the transverse momentum (pT) dependence of v2. The deep learning model is...
Exploring the space-time extent of particle production is an important goal of heavy-ion physics, and substantial effort has been made in order to understand the underlying physics behind the experimental observations of non-Gaussian behavior, in particular with respect to connections to the phase diagram. In experiments, femtoscopic (momentum) correlations are utilized to gain information...
The spin Hall effect (SHE) is a generation of spin polarization for moving spin carriers in materials under an external electric field and has been observed in semiconductors, metals, and insulators at or below room temperature. Recent theoretical analyses show that spin Hall current can be induced by the baryon chemical potential gradient which plays the role of the analogous electric field...
The kinetic-theory-wise formulation of relativistic dissipative nonresistive magnetohydrodynamics for massive spin-half particles in the presence of a magnetic field is presented. Using a relaxation-time approximation for the collision kernel of the underlying relativistic Boltzmann equation the nonequilibrium corrections to the phase-space distribution function and multiple transport...
The statistical hadronization model is very successful in reproducing the experimental data in Pb-Pb collisions, both for light-quark and heavy-quark hadrons. In particular the detailed comparisons for charmonium lead us to infer quasi-complete thermalization of charm quarks in QGP and concurrent hadronization with the lighter quarks. The large yield measured for the Λc baryon at the LHC can...
As a hadronization model in relativistic heavy-ion collisions, coalescence (recombination) model has achieved great success in the description of the production of hadron and light nuclei. This talk focuses on light-nuclei production within the framework of the coalescence model. By employing the characteristic function of the phase space density, we derive the yield of light nuclei in terms...
We describe multiquark clusters in quark matter within a Beth-Uhlenbeck approach in a background gluon field that is coupled to the underlying chiral quark dynamics using the Polyakov-gauge and an effective potential for the traced Polyakov-loop. A higher multiquark cluster of size n is described as a binary composite of smaller subclusters n1 and n2 (n1+n2=n ) with a bound state and...
