Towards a tensionless string field theory for the N=(2,0) CFT in d=6
Sudarshan Ananth, Stefano Kovacs, Yuki Sato +1
We describe progress in using the field theory of tensionless strings to arrive at a Lagrangian for the six-dimensional conformal theory. We construct the free p…
On membrane interactions and a three-dimensional analog of Riemann surfaces
Stefano Kovacs, Yuki Sato, Hidehiko Shimada
Membranes in M-theory are expected to interact via splitting and joining processes. We study these effects in the pp-wave matrix model, in which they are associated with transition…
Membranes from monopole operators in ABJM theory: large angular momentum and M-theoretic AdS_4/CFT_3
Stefano Kovacs, Yuki Sato, Hidehiko Shimada
We consider states with large angular momentum to facilitate the study of the M-theory regime of the AdS_4/CFT_3 correspondence. We study the duality between M-theory in AdS_4xS^7/…
Gauge-invariant correlation functions in light-cone superspace
Sudarshan Ananth, Stefano Kovacs, Sarthak Parikh
We initiate a study of correlation functions of gauge-invariant operators in N=4 super Yang-Mills theory using the light-cone superspace formalism. Our primary aim is to develop ef…
A manifestly MHV Lagrangian for N=4 Yang-Mills
Sudarshan Ananth, Stefano Kovacs, Sarthak Parikh
We derive a manifestly MHV Lagrangian for the N=4 supersymmetric Yang-Mills theory in light-cone superspace. This is achieved by constructing a canonical redefinition which maps th…
Instantons and Supersymmetry
Massimo Bianchi, Stefano Kovacs, Giancarlo Rossi
The role of instantons in describing non-perturbative aspects of globally supersymmetric gauge theories is reviewed. The cases of theories with N=1, N=2 and N=4 supersymmetry are d…
