Double Scaling Limits in Gauge Theories and Matrix Models
Gaetano Bertoldi, Timothy J. Hollowood, J. Luis Miramontes
We show that gauge theories with an adjoint chiral multiplet admit a wide class of large-N double-scaling limits where is taken to infinity in a way coordinated with a t…
S-duality of the Leigh-Strassler Deformation via Matrix Models
Nick Dorey, Timothy J. Hollowood, S. Prem Kumar
We investigate an exactly marginal N=1 supersymmetric deformation of SU(N) N=4 supersymmetric Yang-Mills theory discovered by Leigh and Strassler. We use a matrix model to compute…
Exact Superpotentials from Matrix Models
Nick Dorey, Timothy J. Hollowood, S. Prem Kumar +1
Dijkgraaf and Vafa (DV) have conjectured that the exact superpotential for a large class of N=1 SUSY gauge theories can be extracted from the planar limit of a certain holomorphic…
World-sheet Instantons via the Myers Effect and N=1^* Quiver Superpotentials
Timothy J. Hollowood, S. Prem Kumar
In this note we explore the stringy interpretation of non-perturbative effects in N=1^* deformations of the A_{k-1} quiver models. For certain types of deformations we argue that t…
The D-Instanton Partition Function
Nick Dorey, Timothy J. Hollowood, Valentin V. Khoze
The D-instanton partition function is a fascinating quantity because in the presence of N D3-branes, and in a certain decoupling limit, it reduces to the functional integral of N=4…
A Brief History of the Stringy Instanton
Nick Dorey, Timothy J. Hollowood, Valentin V. Khoze
The arcane ADHM construction of Yang-Mills instantons can be very naturally understood in the framework of D-brane dynamics in string theory. In this point-of-view, the mysterious…
