Recently there was significant progress in account for several lower
harmonics of the ``Little Bang", especially the so called triangular flow,
ascribed to fluctuations of the initial conditions. We discuss this
problem more generally, combining many harmonics coherently into
certain patterns of sound propagation. Analytic solution for all harmonics
is found for the so called ``Gubser...

The measurements of charged-particle multiplicity and transverse energy
in Pb-Pb collisions at 2.76 ATeV are reported as a function of centrality. The fraction of inelastic cross section seen by the ALICE detector is estimated using a Glauber model or correcting the data by simulations. The results scaled by the number of participating nucleons are compared with pp collisions at the same...

The pseudorapidity and centrality dependence of transverse energy and charged particle multiplicities offers insight into the properties of the matter produced in the collisions of ultra-relativistic heavy nuclei. Multiplicities as a function of center-of-mass energy and collision centrality are important for exploring the role of hard and soft scattering in particle production and for looking...

Charged particle multiplicity is an important bulk observable for heavy ion collisions. It measures the global features of the medium produced and constrains the initial conditions of the system. It also provides an important test for dynamical model calculations which predict the dependence of multiplicity on centrality at RHIC and the LHC. We present the study of charged particle...

The expansion of the fireball created in Pb-Pb collisions at $\sqrt{s}=2.76$TeV is modelled using the relativistic viscous hydrodynamics. The experimentally observed interferometry radii are well reproduced. The recent data of the ALICE Collaboration on the elliptic flow as function of the centrality can be very well described using the hydrodynamic expansion of a fluid with a small shear...

(for the ALICE Collaboration)
The relative rates of single‐ and double‐ diffractive processes were measured with the ALICE detector by studying properties of gaps in the pseudorapidity distribution of particles produced in proton‐proton collisions at \sqrt{s} = 0.9 TeV, 2.76 TeV and 7 TeV. ALICE triggering efficiencies were determined for various classes of events, using a detector...
