  We calculate the connected stress-tensor correlation functions that are dual
to a certain class of graviton scattering amplitudes in an asymptotically
anti-de Sitter, black brane spacetime. This is a continuation of a previous
study in which one-particle-irreducible amplitudes were calculated for
arbitrarily higher-derivative gravity in a particular kinetic regime of high
energies and large scattering angles. The utility of this regime is twofold: It
is particularly well suited for translating scattering amplitudes into the
language of the gauge theory and it emphasizes the contributions from
higher-derivative corrections (which would otherwise be perturbatively
suppressed). Using the new results, we show how it could be possible to
identify, experimentally, the gravitational dual to a strongly coupled fluid
such as the quark-gluon plasma.
