F^5 contributions to the nonabelian Born Infeld action from a supersymmetric Yang-Mills five-point function
Andrea Refolli, Alberto Santambrogio, Niccolo' Terzi +1
We consider the N=4 supersymmetric Yang-Mills theory in four dimensions. We compute the one-loop contributions to the effective action with five external vector fields and compare…
Non abelian N=2 supersymmetric Born Infeld action
A. Refolli, N. Terzi, D. Zanon
We present a N=2 supersymmetric action for the Born Infeld theory in the non abelian case. We quantize the theory in N=1 superspace and compute divergences at one-loop. The result…
Three-graviton scattering and recoil effects in M-atrix theory
Andrea Refolli, Niccolo' Terzi, Daniela Zanon
We study the scattering of three gravitons in M-atrix theory at finite N. With a specific choice of the background we obtain the complete result up to two loops. The contributions…
Geometry and beta-functions for N=2 matter models in two dimensions
Silvia Penati, Andrea Refolli, Alexander Sevrin +1
We study renormalizable nonlinear sigma-models in two dimensions with N=2 supersymmetry described in superspace in terms of chiral and complex linear superfields. The geometrical s…
The nonminimal scalar multiplet: duality, sigma-model, beta-function
Silvia Penati, Andrea Refolli, Antoine Van Proeyen +1
We compute in superspace the one-loop beta-function for the nonlinear sigma-model defined in terms of the nonminimal scalar multiplet. The recently proposed quantization of this co…
Quantum boundary currents for nonsimply-laced Toda theories
Silvia Penati, Andrea Refolli, Daniela Zanon
We study the quantum integrability of nonsimply--laced affine Toda theories defined on the half--plane and explicitly construct the first nontrivial higher--spin charges in specifi…
