Instanton-induced Yang-Mills correlation functions at large N and their AdS_5xS^5 duals
Michael B. Green, Stefano Kovacs
Correlation functions of chiral primary operators and their superconformal descendants in the N=4 supersymmetric SU(N) Yang-Mills theory are studied in detail in a one-instanton ba…
Supersymmetry and Branes in M-theory Plane-waves
Nakwoo Kim, Jung-Tay Yee
We study brane embeddings in M-theory plane-waves and their supersymmetry. The relation with branes in AdS backgrounds via the Penrose limit is also explored. Longitudinal planar b…
Remarks on type IIB pp waves with Ramond-Ramond fluxes and massive two dimensional nonlinear sigma models
Nakwoo Kim
We continue the study of supersymmetric type IIB pp wave solutions by Maldacena and Maoz (hep-th/0207284), who showed Ramond-Ramond five-forms can induce potential terms in the lig…
Gravitational corrections in supersymmetric gauge theory and matrix models
Albrecht Klemm, Marcos Marino, Stefan Theisen
Gravitational corrections in N=1 and N=2 supersymmetric gauge theories are obtained from topological string amplitudes. We show how they are recovered in matrix model computations.…
Are there really any AdS_2 branes in the euclidean (or not) AdS_3?
Benedicte Ponsot, Sebastian Silva
We do not find any AdS_2 branes, neither in the H_3^+ WZNW model nor the SL(2,R) WZNW model. We then reexamine the case of the branes that possess a su(2) symmetry: we speculate th…
PP-Wave Light-Cone Superstring Field Theory
A. Pankiewicz, B. Stefanski
We construct the cubic interaction vertex and dynamically generated supercharges in light-cone superstring field theory in the pp-wave background. We show that these satisfy the pp…
