Query: Pressure isotropization in high energy heavy ion collisions   The early stages of high energy heavy ion collisions are studied in the Color
Glass Condensate framework, with a real-time classical lattice simulation. When
increasing the coupling constant, we observe a rapid increase of the ratio of
longitudinal to transverse pressure. The transient regime that precedes this
behavior is of the order of 1 fm/c.
