(The mass appears since $p/M = v/√(1-v^2)$.) drag was derived for a static medium: it was generalized to the case of Bjorken hydrodynamics corresponding to the Janik-Peschanski metric JP_metric in [ref] with the conclusion that drag still applies in this dynamic case if one replaces $T →T(τ)$ in it, with $T(τ)$ given by Temp.

One usually approximates the nuclear profiles by delta-functions: defining $t_1 (x^-) ≡ 2 π^2/N_c^2 ⟨T_1^++ (x^-) ⟩$ and $t_2 (x^+) ≡ 2 π^2/N_c^2 ⟨T_2^– (x^+) ⟩$ for the EMT's of the two shock waves, we have [equation] with [ref] [equation] Here $p_1^+$, $p_2^-$ are the large light-cone momenta per nucleon in the two nuclei with atomic numbers $A_1$ and $A_2$, while $Λ_1$ and $Λ_2$ are the typical transverse momentum scales describing the two nuclei.

For the sourceless delta-function shock waves of Eqs. 1nuc, deltas the produced entropy per unit transverse area $A_⊥$ was found to be [ref] [equation] The thermalization (black hole formation) proper time is given by the only dimensionful boost-invariant parameter in the problem ($μ_1 μ_2$) [ref] as [equation] which, as can be seen from mus, is very short parametrically, being suppressed by a power of the center of mass energy $s$ as $μ_1 μ_2 ∼p_1^+ p_2^- ∼s$.

It is worth noting here that the numerical simulations of [ref] give $0.35$ fm/c as the time interval between when the Gaussian shocks used in the simulations start to overlap significantly to the onset of viscous hydrodynamics in RHIC kinematics.

However, note that to properly compare thermalization time with the hydrodynamic simulations [ref] one has to start measuring the proper time from $τ=0$, i.e., from the moment of the complete overlap of the two shocks: such procedure, when applied to the results of [ref] , yields the thermalization time of about $τ_th ≈0.17$ fm/c, much closer to thermtime and further away from the phenomenological times.
