(2,0) lagrangian structures

Abstract

By including an additional self-dual three-form we construct a Lorentz invariant lagrangian for the abelian (2,0) tensor supermultiplet. The extra three-form is a supersymmetry singlet and decouples from the (2,0) tensor supermultiplet. We also present an interacting non-abelian generalization which reproduces the equations of motion of [1] and can describe some aspects of two interacting M5-branes.
