The authors' main claim For phenomenological purposes, our main result is that, when a quark is created within the plasma together with its corresponding antiquark, the quark starts feeling the plasma only after the q-\bar{q} separation becomes larger than the (v-dependent) screening length, and from this point on the motion is correctly described by the analytic energy loss formula previously derived by Herzog et al. and Gubser within the stationary or late-time approximations.

We give a brief overview of the results obtained in arXiv:0803.3070, concerning the rate of energy loss of an accelerating quark in strongly-coupled N=4 super-Yang-Mills, both at zero and finite temperature. For phenomenological purposes, our main result is that, when a quark is created within the plasma together with its corresponding antiquark, the quark starts feeling the plasma only after the q-\bar{q} separation becomes larger than the (v-dependent) screening length, and from this point on the motion is correctly described by the analytic energy loss formula previously derived by Herzog et al. and Gubser within the stationary or late-time approximations. The present text is a slightly expanded version of two talks given at the XIII Mexican School of Particles and Fields in October 2008.

In [ref] , building upon the previous work [ref] , we have numerically studied the evolution of a heavy quark and antiquark that are created within the plasma at time $t=0$ and then separate back to back.

A thorough generalization of Mikhailov's analytic results [ref] to this finite temperature setup would require finding the exact solution to the Nambu-Goto equation of motion for the string on the AdS-Schwarzschild background, for any given trajectory of the string endpoint at $z_m≥0$.

Following [ref] , this translates into $z_m/z_h∼0.16-0.40$ for charm and $z_m/z_h∼0.046-0.11$ for bottom.

That is to say, unlike what we found for the forced isolated quark in Section [ref], here there is no intermediate stage where the quark and antiquark decelerate independently from one another at a rate that differs substantially from the late-time result of [ref] .

This picture seems rather close to the phenomenological discussion given in [ref] (in the context of collisional energy loss): when the singlet quark-antiquark pair is formed within the plasma, there is a delay before the interaction between the newly created sources and the plasma can set up the long range gluonic field profile that is responsible for the late-time dissipation.
