Measurements of the $v_2$ of identified hadrons and of azimuthal
correlations between rapidity separated soft particles strongly
suggest the presence of collective effects in central $d$$+$Au
collisions at $\sqrt{s_{NN}}$=200 GeV. The good agreement between
low viscosity hydrodynamic calculations and experimental results
also suggests a close relationship between the effects observed...

Anisotropic flow plays a critical role in establishing the equation of state for the Quark Gluon Plasma. The results at the LHC have demonstrated that the matter created in heavy-ion collisions behaves as a nearly perfect fluid reflected in the low value of the shear viscosity over entropy density ratio ($\eta$/s). The higher flow harmonics are particularly sensitive to the value of $\eta$/s...

A Principle Component Analysis (PCA) of two-particle azimuthal correlations as a function of transverse momentum ($p_T$) is presented in PbPb collisions at 2.76 TeV and high-multiplicity pPb collisions at 5.02 TeV. The data were recorded using the CMS detector at the LHC. It has recently been shown that factorization breaking of two-particle azimuthal correlations can be attributed to the...

We compute the initial fluctuating QCD-matter energy densities produced in ultrarelativistic heavy-ion collisions from NLO perturbative QCD using a saturation conjecture to control soft particle production [1], and describe the subsequent space-time evolution of the system with dissipative fluid dynamics [2], event by event [3]. The resulting centrality dependence of hadronic multiplicities,...

It is commonly believed that azimuthal anisotropies in relativistic heavy ion collisions are generated by hydrodynamic evolution of the strongly interacting quark-gluon plasma. Recently, apparent anisotropy signals have been observed in small systems of proton- and deuteron-nucleus collisions, and the signals can again be described by hydrodynamics. A natural question is why hydrodynamics...
