Medium induced parton energy loss is not conclusively established neither in very peripheral heavy-ion collisions nor in proton-ion collisions. However, the standard interpretation of azimuthal momentum anisotropies in theses systems implies some …
We investigate the measurement of Hanbury Brown-Twiss (HBT) photon correlations as an experimental tool to discriminate different sources of photon enhancement, which are proposed to simultaneously reproduce the direct photon yield and the azimuthal …
We use experimentally measured identified particle spectra and Hanbury Brown-Twiss radii to determine the entropy per unit rapidity dS/dy produced in $\sqrt{s}=7~\text{TeV}$ pp and $\sqrt{s_{NN}}=2.76~\text{TeV}$ Pb-Pb collisions. We find that …
We use a thermal model with single freeze-out to determine longitudinal polarization of $\Lambda$ hyperons emitted from a hot and rotating hadronic medium. We consider the top RHIC energies and use the model parameters determined in the previous …
We develop a macroscopic description of the space-time evolution of the energy-momentum tensor during the pre-equilibrium stage of a high-energy heavy-ion collision. Based on a weak coupling effective kinetic description of the microscopic …
Hydrokinetic theory of thermal fluctuations is applied to a nonconformal relativistic fluid. Solving the hydrokinetic equations for an isotropically expanding background we find that hydrodynamic fluctuations give ultraviolet divergent contributions …
We develop a set of kinetic equations for hydrodynamic fluctuations which are equivalent to nonlinear hydrodynamics with noise. The hydrokinetic equations can be coupled to existing second-order hydrodynamic codes to incorporate the physics of these …
We analyze the spectrum of harmonic flow, vn(pT) for n=0–5, in event-by-event hydrodynamic simulations of Pb+Pb collisions at the CERN Large Hadron Collider (sNN=2.76TeV) with principal component analysis (PCA). The PCA procedure finds two dominant …
We perform a principal component analysis (PCA) of v3(pT) in event-by-event hydrodynamic simulations of Pb+Pb collisions at the Large Hadron Collider (LHC). The PCA procedure identifies two dominant contributions to the two-particle correlation …
