We propose an all-order perturbative expression for the dressing phase of the AdS5 × S string S-matrix at strong coupling. Moreover, we are able to sum up large parts of this expression. This allows… (More)

One-loop corrections to the energy of semiclassical rotating strings contain both analytic and non-analytic terms in the ’t Hooft coupling. Analytic contributions agree with the prediction from the… (More)

The ferromagnetic integrable SU(3) spin chain provides the one loop anomalous dimension of single trace operators involving the three complex scalars of N = 4 supersymmetric Yang-Mills. We construct… (More)

We consider configurations of Neveu-Schwarz fivebranes, Dirichlet fourbranes and an orientifold sixplane in type IIA string theory. Upon lifting the configuration to M-theory and proposing a… (More)

Atmospheric nitrogen deposition, associated with chronic urban air pollution, has produced stream water nitrate concentrations as high as 7.0 mg of N L-l in chaparral watersheds in the San Gabriel… (More)

We study brane configurations in the presence of orientifold six-planes. After deriving the curves for N = 2 supersymmetric SU(Nc) gauge theories with one flavor in the symmetric or antisymmetric… (More)

Using a six-orientifold, fourbranes and four fivebranes in type IIA string theory we construct N=1 supersymmetric gauge theories in four dimensions with product group SU(M)×SO(N) or SU(M)×Sp(2N), a… (More)

N = 4 supersymmetric Yang-Mills operators carrying large charges are dual to semiclassical strings in AdS5 × S. The spectrum of anomalous dimensions of very large operators has been calculated… (More)

We discuss UV/IR mixing effects in non-supersymmetric noncommutative U(N) gauge theories. We show that the singular (nonplanar) terms in the 2and 3-point functions, namely the poles and the… (More)

Using a six-orientifold on top of a NS-fivebrane we construct a chiral N = 1 supersymmetric gauge theory in four dimensions with gauge group SU(Nc) and matter in the symmetric, antisymmetric and… (More)
