N = 2 Gauge/Gravity Duals
Joseph Polchinski
We study the N = 2 supersymmetric analog of the Klebanov-Strassler system. We first review the resolution of singularities by the enhancon mechanism, and the physics of fractional…
Supersymmetric Three-Form Flux Perturbations on
Mariana Graña, Joseph Polchinski
We consider warped type IIB supergravity solutions with three-form flux and supersymmetry, which arise as the supergravity duals of confining gauge theories. We first…
Gauge Dual and Noncommutative Extension of an N=2 Supergravity Solution
Alex Buchel, Amanda W. Peet, Joseph Polchinski
We investigate some properties of a recent supergravity solution of Pilch and Warner, which is dual to the N=4 gauge theory softly broken to N=2. We verify that a D3-brane probe ha…
Quantization of Four-form Fluxes and Dynamical Neutralization of the Cosmological Constant
Raphael Bousso, Joseph Polchinski
A four-form gauge flux makes a variable contribution to the cosmological constant. This has often been assumed to take continuous values, but we argue that it has a generalized Dir…
The String Dual of a Confining Four-Dimensional Gauge Theory
Joseph Polchinski, Matthew J. Strassler
We study N=1 gauge theories obtained by adding finite mass terms to N=4 Yang-Mills theory. The Maldacena dual is nonsingular: in each of the many vacua, there is an extended brane…
