Unfolding the Six-Dimensional Tensor Multiplet

Abstract

We derive a manifestly superconformally covariant unfolded formulation of the free (2,0) tensor multiplet in six spacetime dimensions. The unfolded system consists of an abelian two-form and an infinite-dimensional chiral zero-form containing the system's curvature, matter fields, and their derivatives on-shell, realized using superoscillators. The construction of the cocycle gluing these forms on a general superconformal background goes one step beyond previous results in super-Poincaré backgrounds.
