Correlations and fluctuations
Experimental
Strong event-by-event fluctuations in the energy density of heavy-ion collisions have been recently observed with ALICE, with the measurement of non-zero odd harmonic anisotropic flow coefficients. This measurement suggests the possibility to select different event shapes for a definite centrality and colliding system. The event selection is based on the azimuthal distribution of produced...

Relativistic hydrodynamic and collective phenomena
Experimental
The higher order flow anisotropies (v_{n}) are considered to be originated from initial geometrical fluctuation of participating nucleons followed by the collective expansion of the hot and dense medium created in high-energy heavy-ion collisions. The source geometry with possible fluctuation at the end of the expansion would depend on the magnitude of the initial fluctuation, the strength of...

Correlations and fluctuations
Experimental
Observation of a long-range near-side two-particle correlation (known as the "Ridge") in high-multiplicity pp and pPb collisions opened up new opportunities of exploring novel QCD dynamics in small collision systems. To further investigate the origin of this phenomenon, studies of two-particle correlations with identified $K^0_s$ and Lambda trigger particles in 5.02 TeV pPb collisions are...

Relativistic hydrodynamic and collective phenomena
Theory
We analyze recent STAR data for the directed flow of protons,
antiprotons and charged pions obtained within the beam energy scan
program within the Parton-Hadron-String-Dynamics (PHSD) transport
model and a 3-Fluid hydroDynamics (3FD) approach. We clarify the role
of partonic degrees of freedom in the the kinetic PHSD approach. The
PHSD results, simulating a partonic phase and its...

Relativistic hydrodynamic and collective phenomena
Theory
Successful applications of relativistic viscous hydrodynamics in the description of heavy-ion collisions at RHIC and the LHC triggered large interest in the development of the hydrodynamic framework. An example of the new approach to relativistic dissipative hydrodynamics is anisotropic hydrodynamics --- the framework where effects connected with the expected high pressure anisotropy of the...

Relativistic hydrodynamic and collective phenomena
Theory
We present a new algorithm for solving ideal relativistic hydrodynamics based on Godunov method with exact solution of Riemann problem with an arbitrary equation of state. Standard numerical tests are executed, such as sound wave propagation and schock tube problem. Low numerical viscosity and high precision are attained with proper discretization.
