Isotropization and Thermalization in Heavy Ion Collisions
We argue that isotropization and, consequently, thermalization of the system of gluons and quarks produced in an ultrarelativistic heavy ion collision does not follow from Feynman diagram analysis to any order in the coupling constant. We conclude that the apparent thermalization of quarks and gluons, leading to success of perfect fluid hydrodynamics in describing heavy ion collisions at RHIC, ...
متن کاملIsotropization and Hydrodynamization in Weakly Coupled Heavy-Ion Collisions.
We numerically solve the (2+1)-dimensional effective kinetic theory of weak coupling QCD under longitudinal expansion, relevant for early stages of heavy-ion collisions. We find agreement with viscous hydrodynamics and classical Yang-Mills simulations in the regimes where they are applicable. By choosing initial conditions that are motivated by a color-glass-condensate framework, we find that f...
متن کاملPressure Isotropization in Heavy Ion Collisions from Color Glass Condensate
It is well known that the quark-gluon plasma (QGP) produced in heavy ion collisions can be successfully described by hydrodynamics; successful hydrodynamics requires rapid thermalization with the thermalization time τ0 less than 1 fm/c [1]. Studying the dynamical processes before the formation of the QGP can provide initial conditions for the hydrodynamic simulations. During the hydrodynamic ev...
متن کاملCollision Thermalization of Nucleons in Relativistic Heavy-Ion Collisions
We consider a possible mechanism of thermalization of nucleons in relativistic heavy-ion collisions. Our model belongs, to a certain degree, to the transport ones; we investigate the evolution of the system created in nucleus-nucleus collision, but we parametrize this development by the number of collisions of every particle during evolution rather than by the time variable. We based on the ass...
متن کاملA Possible Modified “bottom-up” Thermalization in Heavy Ion Collisions∗
We present a possible scaling solution to pre-equilibrium evolution which interpolates between the instability present in the dense gluon system produced immediately after a heavy ion collision and the final equilibration which occurs later. Our solution depends on a single parameter δ. Depending on the value of δ, our proposed solution matches onto the bottom-up picture either at an intermedia...
