We study the influence of the baryon chemical potential $\mu_B$ on the dynamical properties of the Quark–Gluon–Plasma (QGP) in and out-of equilibrium. The description of the QGP in equilibrium is based on the effective propagators and couplings from the Dynamical QuasiParticle Model (DQPM)that is matched to reproduce the equation-of-state of the partonic system above the...
Fluctuations of conserved charges carry rich information about the fine details of the QCD equation of state.
Recent lattice QCD data on high order baryon number susceptibilities are used here to constrain the excluded volume corrections in the hadron resonance gas model.
I will then address the question of comparison between experimental measurements of baryon and proton number fluctuations...
We review experimental results on the direct and isolated photon production in pp, pA and AA collisions at different colliding energies and compare them with theoretical calculations. We discuss thermal direct photon production in AA collisions and consider several proposed solutions of “direct photon flow puzzle” - a strong measured collective flow of direct photons, comparable with the one...
Finite baryon density induces a mixing between the vector and axial-vector states, and
yields multiple bumps and peaks around the vacuum masses of the $\rho, \omega$ and $\phi$ resonances in the spectral function. The modification become significantly pronounced when the mass difference between the parity partners decreases in dense matter.
We propose that the emergent enhancement in the...
Thermal vorticity in non-central Au+Au collisions at energies 7.7≤s√≤62.4 GeV is calculated within the microscopic transport model UrQMD. The whole volume of an expanding fireball is subdivided into small cubic cells. Then we trace the final Λ and Λ¯ hyperons back to their last interaction point within a certain cell. Extracting the bulk parameters of hot and dense medium in the cell, one can...
