Initial state fluctuations and final state correlations: Status and open questions
Andrew Adare, Matthew Luzum, Hannah Petersen
The recent appreciation of the importance of event-by-event fluctuations in relativistic heavy-ion collisions has lead to a large amount of diverse theoretical and experimental act…
Breaking of factorization of two-particle correlations in hydrodynamics
Fernando G. Gardim, Frederique Grassi, Matthew Luzum +1
The system formed in ultrarelativistic heavy-ion collisions behaves as a nearly-perfect fluid. This collective behavior is probed experimentally by two-particle azimuthal correlati…
Characterizing the hydrodynamic response to the initial conditions
Fernando G. Gardim, Frederique Grassi, Matthew Luzum +1
In hydrodynamics, the momentum distribution of particles at the end of the evolution is completely determined by initial conditions. We study quantitatively to what extent anisotro…
Hydro overview
Jean-Yves Ollitrault, Fernando G. Gardim
We review recent progress in applying relativistic hydrodynamics to the modeling of heavy-ion collisions at RHIC and LHC, with emphasis on anisotropic flow and flow fluctuations.
Extracting the shear viscosity of the quark-gluon plasma from flow in ultra-central heavy-ion collisions
Matthew Luzum, Jean-Yves Ollitrault
We propose a method for extracting the shear viscosity over entropy density ratio (eta/s) of the quark-gluon plasma from experimental data. We argue that uncertainty due to poor kn…
Half-Skyrmions and the Equation of State for Compact-Star Matter
Huan Dong, T. T. S. Kuo, Hyun Kyu Lee +2
The half-skyrmions that appear in dense baryonic matter when skyrmions are put on crystals modify drastically hadron properties in dense medium and affect strongly the nuclear tens…
