We evaluate the free energy of the Yang-Mills theory using the Gribov quantization that copes with non-perturbative resummation. The magnetic scale is automatically incorporated in the framework and we find it efficient to stabilize the perturbative expansion of the free energy. In the range of the temperature T=Tc~2Tc major uncertainty in our results comes from the non-perturbative running...

Anomaly induced transport effects, like the Chiral Magnetic Effect or the Chiral Separation Effect, have recently attracted much attention and are expected to be observed in ultra-relativistic heavy-ion collisions. So far, the evidence in the experiments has been elusive, mainly due to the lack of quantitative theoretical predictions. In order to asses the contributions from anomalous...

Every dynamical description of heavy-ion collisions --whether based on hydrodynamics or on a parton cascade-- starts out with the modeling of the 'initial condition', i.e. the state of the system after the first initial energetic collisions between target and projectile nucleons. Usually it is assumed that the whole system or at least the quark-gluon plasma comes to a thermal equilibrium...

Multi-parton interactions (MPI) is a key ingredient in the successful
phenomenological description of hadron-hadron collisions. In the
hadronization of MPI, final partons originating from different partonic
sub-collisions can interact with each other through color strings: the
so-called color reconnection (CR) mechanism. In this work we show that
CR produces a radial flow-like effect...

Recently, the higher harmonics v_n (n>2) are systematically observed at RHIC and LHC and attract a lot of theoretical and experimental interests. Initial state fluctuations turned out to be important to explain these higher harmonics through event-by-event hydrodynamic simulations. In addition attempts are made to extract transport properties of the created matter such as shear viscosity from...

A current goal of relativistic heavy ion collisions experiments
is the search for a Color Glass Condensate (CGC) as the limiting state of QCD matter at very high density.
In viscous hydrodynamics simulations, a standard Glauber initial condition leads to estimate $4\pi \eta/s \sim 1$, while employing the Kharzeev-Levin-Nardi (KLN) modeling of the glasma leads to at least a factor of 2 larger...
