Arbitrary Superspin Massive Superparticles

Abstract

We propose the action for a massive $N$-extended superparticle with a pure (half)integer superspin $Y,Y=0,1/2,1,3/2,\dots$. Regardless of the superspin value, the configuration space is ${\mathbb{R}}^{4|4N}\times S^2$, where $S^2$ corresponds to spinning degrees of freedom. Being explicitly super-Poincaré invariant, the model possesses two gauge symmetries implying strong conservation of the squared momentum and superspin. Hamilton constrained dynamics is developed and canonical quantization is studied. For $N$ = 1 we show that the physical super wave-functions are to be on-shell massive chiral superfields. Central-charges generalizations of the model are given.
