Subleading-color contributions to gluon-gluon scattering in N=4 SYM theory and relations to N=8 supergravity
Stephen G. Naculich, Horatiu Nastase, Howard J. Schnitzer
We study the subleading-color (nonplanar) contributions to the four-gluon scattering amplitudes in N=4 supersymmetric SU(N) Yang-Mills theory. Using the formalisms of Catani and of…
Two-loop graviton scattering relation and IR behavior in N=8 supergravity
Stephen G. Naculich, Horatiu Nastase, Howard J. Schnitzer
We derive an ABDK-like relation between the one- and two-loop four-graviton amplitudes in N=8 supergravity. Specifically we show that the infrared divergent part of the two-loop am…
Regge behavior of gluon scattering amplitudes in N=4 SYM theory
Stephen G. Naculich, Howard J. Schnitzer
It is shown that the four-gluon scattering amplitude for N=4 supersymmetric Yang-Mills theory in the planar limit can be written, in both the weak- and strong-coupling limits, as a…
Level-rank duality of untwisted and twisted D-branes of the so(N)_K WZW model
Stephen G. Naculich, Benjamin H. Ripman
We analyze the level-rank duality of untwisted and epsilon-twisted D-branes of the so(N)_K WZW model. Untwisted D-branes of so(N)_K are characterized by integrable tensor and spino…
Many roads lead to N=2 Seiberg-Witten theory
Stephen G. Naculich, Howard J. Schnitzer
The Seiberg-Witten solution plays a central role in the study of N=2 supersymmetric gauge theories. As such, it provides a proving ground for a wide variety of techniques to treat…
Elliptic Fibrations and Elliptic Models
Amy E. Ksir, Stephen G. Naculich
We study the Seiberg-Witten curves for N=2 SUSY gauge theories arising from type IIA string configurations with two orientifold sixplanes. Such theories lift to elliptic models in…
