Dissipative hydrodynamics and heavy ion collisions
Space-time evolution and subsequent particle production from minimally viscous (η/s=0.08) QGP fluid is studied using the 2nd order Israel-Stewart’s theory of dissipative relativistic fluid. Compared to ideal fluid, energy density or temperature evolves slowly in viscous dynamics. Particle yield at high pT is increased. Elliptic flow on the other hand decreases in viscous dynamics. Minimally vis...
متن کاملRelativistic hydrodynamics for heavy-ion collisions
Relativistic hydrodynamics is essential to our current understanding of nucleus-nucleus collisions at ultrarelativistic energies (current experiments at the Relativistic Heavy Ion Collider, forthcoming experiments at the CERN Large Hadron Collider). This is an introduction to relativistic hydrodynamics for graduate students. It includes a detailed derivation of the equations, and a description ...
متن کاملMacroscopic quasimolecules in dissipative heavy-ion collisions
Long-range quasiperiodic correlations in fluctuating excitation functions of dissipative heavy-ion collisions are obtained from a pole representation for the S-matrix elements. The time power spectra of a decaying dinuclear system shows a time-orientation localization as if it rotates like a classical object. This allows one to interpret the correlations in terms of the formation of specific nu...
متن کاملResults of the Hydrodynamics Approach to Heavy Ion Collisions
One of the first measurements at RHIC was the elliptic anisotropy of the particles produced [1]. It was found to be as large as the hydrodynamical prediction [2] and subsequent hydrodynamical calculations achieved good fits to its centrality and pT dependence [3,4,5]. In the following I review how well hydrodynamical models can fit the data published after those early papers and what constraint...
متن کاملFourier analysis of nonself-averaging quasiperiodic oscillations in the excitation functions of dissipative heavy-ion collisions: quantum chaos in dissipative heavy-ion collisions?
We employ stochastic modelling of statistical reactions with memory to study quasiperiodic oscillations in the excitation functions of dissipative heavy-ion collisions. The Fourier analysis of excitation function oscillations is presented. It suggests that S-matrix spin and parity decoherence, damping of the coherent nuclear rotation and quantum chaos are sufficient conditions to explain the no...
