Off-shell kappa-symmetry of the superparticle and the spinning superparticle

The spinorial local world-line κ-symmetry of the covariant Brink-Schwarz formulation of the 4-D superparticle is abelian in an off-shell phase-space formulation. The result is shown to generalize to the extended spinorial transformations of the spinning superparticle. © 1998 Elsevier Science B.V. All rights reserved.
