Mixing of the RR and NSNS sectors in the BMN limit
Michael B. Green, Stefano Kovacs, Aninda Sinha
This paper concerns instanton contributions to two-point correlation functions of BMN operators in N=4 supersymmetric Yang-Mills that vanish in planar perturbation theory. Two-poin…
Non-Perturbative Contributions in the Plane-Wave/BMN Limit
Michael B. Green, Stefano Kovacs, Aninda Sinha
This talk surveys recent work on the contribution of instantons to the anomalous dimensions of BMN operators in $\calN=4$ supersymmetric Yang--Mills theory and the corresponding no…
Non-perturbative effects in the BMN limit of N=4 supersymmetric Yang-Mills
Michael B. Green, Stefano Kovacs, Aninda Sinha
One-instanton contributions to the correlation functions of two gauge-invariant single-trace operators in N=4 SU(N) Yang-Mills theory are studied in semi-classical approximation in…
Warped Tachyonic Inflation in Type IIB Flux Compactifications and the Open-String Completeness Conjecture
Daniel Cremades, Fernando Quevedo, Aninda Sinha
We consider a cosmological scenario within the KKLT framework for moduli stabilization in string theory. The universal open string tachyon of decaying non-BPS D-brane configuration…
Non-perturbative contributions to the plane-wave string mass matrix
Michael B. Green, Stefano Kovacs, Aninda Sinha
D-instanton contributions to the mass matrix of arbitrary excited string states of type IIB string theory in the maximally supersymmetric plane-wave background are calculated to le…
