Kinetic description of mixtures of anisotropic fluids

Understand

A simple system of coupled kinetic equations for quark and gluon anisotropic systems is solved numerically.

• The solutions are compared with the predictions of the anisotropic hydrodynamics describing a mixture of anisotropic fluids.
• We find that the solutions of the kinetic equations can be well reproduced by anisotropic hydrodynamics if the initial distribution are oblate for both quarks and gluons.
• On the other hand, the solutions of the kinetic equations have a different qualitative behavior from those obtained in anisotropic hydrodynamics if the initial configurations are oblate-prolate or prolate-prolate.
