Description
Early stages before hydrodynamization in heavy ion collision is studied by numerically solving a 2+1D effective kinetic theory of weak coupling QCD under longitudinal
expansion. 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 color-glass-condensate framework we find that for Qs = 2GeV and αs = 0.3, the system is approximately described by viscous hydrodynamics well before τ ~ 1.0 fm/c.
