Toward the AdS/CFT gravity dual for high energy collisions. II. The stress tensor on the boundary

In this second paper of the series, we calculate the stress tensor of excited matter, created by debris of high energy collisions at the boundary. The falling open strings, connected to receding charges, produce a nonzero stress tensor which we found analytically from time-dependent linearized Einstein equations in the bulk. It corresponds to exploding nonequilibrium matter: we discuss its behavior in some detail, including its internal energy density in a comoving frame and the freeze-out surfaces. We then discuss what happens for the ensemble of strings.
