Direct evidence for the Maldacena conjecture for N=(8,8) super-Yang-Mills theory in 1+1 dimensions

We solve N=(8,8) super-Yang-Mills theory in 1+1 dimensions at strong coupling to directly confirm the predictions of supergravity at weak coupling. We do our calculations in the large-Nc approximation using Supersymmetric Discrete Light-Cone Quantization with up to 3×1012 basis states. We calculate the stress-energy correlator 〈T++(r)T++(0)〉 as a function of the separation r and find that at intermediate values of r the correlator behaves as r−5 to within errors as predicted by weak-coupling supergravity. We also present an extension to significantly higher resolution of our earlier results for the same correlator in the N=(2,2) theory and see that in this theory the correlator has very different behavior at intermediate values of r.
