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)

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)

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)

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)

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)

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)

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, 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)
