Four-points two-loop scattering amplitude in ABJM theory

Penati S.; Santambrogio, A.

Abstract

Within the ?? = 2 superspace perturbative formulation of ABJM theory, we derive the set of scalar Feynman integrals describing the four-point scattering amplitude of chiral matter fields. Using dimensional regularization (D = 3 - 2?), we evaluate the integrals on-shell and we compare the result with that of a Wilson-loop computed in a light-like tetragon contour: we find matching results between both calculations after identifying the kinematical invariants. We discuss further implications and open questions. This work is a contribution to the proceedings of the XVIIth European Workshop on String Theory 2011 held in Padua, Italy, on September 2011.
