“…The properties of matter change considerably in a small spacetime domain, characterized by a time-scale, τ ′ (τ ), which governs the process. Here, we recall the assumption for the escape rate [21,22], which characterizes the freezeout of matter in finite time, L, the proper time interval between two parallel hypersurfaces, where the continuous freeze-out of matter starts at τ 0 and ends at τ 0 + L, thus…”
