Anisotropic flow is an important observable to study the properties and the evolution of the system created in heavy-ion collisions. We present measurements of anisotropic flow of strange and multi-strange particles, including Ks, Λ, Ξ, Ω and φ, in Pb–Pb collisions at \sqrt{s_{NN}} = 2.76 TeV recorded with the ALICE detector. The results are compared to hydrodynamic model calculations,...

ATLAS has performed a detailed measurement of event-by-event flow in
lead-lead collisions at the LHC. The Fourier coefficients, v2-v4, of the
azimuthal angle distribution of charged particles measured in the
ATLAS inner detector (|eta| < 2.5) are extracted in each of 48 million
minimum-bias Pb+Pb collisions. The v2-v4 distributions are measured for a
variety of centrality intervals over...

At first, we exactly solve the relaxation-time approximation Boltzmann equation for a system which is transversely homogeneous and undergoing boost-invariant longitudinal expansion. We compare the resulting exact numerical solution with approximate solutions available in the anisotropic hydrodynamics and second order viscous hydrodynamics frameworks. In all cases studied, we find that the...

The study of the transverse momentum anisotropy of the particles produced in heavy ion collisions is one of the most important experimental observable to investigate the collective behavior of the systems created in such collisions. Recent studies show that the complexity of the nature of the system evolution, such as initial condition fluctuations and jets, may lead to important effects in...

Landau solution of hydrodynamics is generalized for the non-central high-energy nuclear collisions. The multiparticle production after hydrodynamic expansion from the transversely asymmetric initial state shows elliptic flow formation.
Moreover, obtained solution does reproduce the observed longitudinal scaling of the elliptic flow for the different collision energies at LHC and RHIC. It...

Theoretical study\cite{myref1} indicates that a chiral magnetic wave at finite baryon density could induce an electric quadrupole moment in QGP produced in heavy-ion collisions. The electric quadrupole deformation will lead to a difference in elliptic flow of hadrons, by increasing {$v_{2}$} of negatively charged hadrons and decreasing {$v_{2}$} of positively charged ones. The magnitude of...
