Description
The Boltzmann Equation in Diffusion Approximation (BEDA) can be used as a tool for exploring the thermalization/hydrodynamization of the quark-gluon plasma. In this talk, we address this issue extending the parametric estimates obtained for small coupling in the so-called bottom-up thermalization by Baier, Mueller, Shiff and Son by introducing quarks and antiquarks in the calculation. Then, we look for confirmation of these estimates with numerical solution of the BEDA. This simulation involves a brand new GPU code capable of solving the BEDA in an arbitrary tridimensional configuration in momentum space. A comparison with the widely used Effective Kinetic Theory will be also shown for different setups. We find an excellent agreement between the two approaches, indicating that the much less numerically expensive BEDA approach is an excellent alternative for more realistic implementations.
