Non-boost-invariant anisotropic dynamics

Martinez, Mauricio, Strickland, Michael

Understand

We study the non-boost-invariant evolution of a quark-gluon plasma subject to large early-time momentum-space anisotropies.

Rather than using the canonical hydrodynamical expansion of the distribution function around an isotropic equilibrium state, we expand around a state which is anisotropic in momentum space and parameterize this state in terms of three proper-time and spatial-rapidity dependent parameters.
Deviations from the Bjorken scaling solutions are naturally taken into account by the time evolution of the spatial-rapidity dependence of the anisotropic ansatz.
As a result, we obtain three coupled partial differential equations for the momentum-space anisotropy, the typical momentum of the degrees of freedom, and the longitudinal flow.
