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 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 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...
متن کاملTheory of multiphonon excitation in heavy-ion collisions.
We study the e ects of channel coupling in the excitation dynamics of giant resonances in relativistic heavy ions collisions. For this purpose, we use a semiclassical approximation to the Coupled-Channels problem and separate the Coulomb and the nuclear parts of the coupling into their main multipole components. In order to assess the importance of multi-step processes, we neglect the resonance...
متن کاملMicroscopic Theory of Multifragmentation in High Energy Heavy-ion Collisions
We introduce a novel N-body approach to describe heavy ion collisions. The nucleons are represented as Gaussian wave packets in configuration and momentum space. They interact via a combination of a Skyrme type potential and a Uehling-Uhlenbeck two-body scattering mechanism. This theory keeps track of the correlations and therefore allows for a selfconsistent theoretical description of the enti...
