Universal description of 3D supersymmetric scalar multiplets for any N.

Framework applicable to lower dimensions via truncation.

Abstract

An explicit construction of theories of spinning particles, both massive and massless, is given with arbitrary extended supersymmetry on the world-line. As an application of our results, we give a universal description of 3D (and via truncation all lower dimensional) supersymmetric scalar multiplets with arbitrary N-extended supersymmetry.
