Dual Anti-de Sitter Superalgebras from Partial Supersymmetry Breaking
The partial breaking of supersymmetry in anti\char21{}de Sitter space can be accomplished using two of four dual representations for the massive $\mathrm{OSp}(1,4)$ spin-3/2 multiplet. The procedure gives rise to a set of dual $N=2$ supergravities and supersymmetry algebras.
Massive supermultiplets with spin 3/2
In this paper we construct massive supermultiplets out of appropriate set of massless ones in the same way as massive spin s particle could be constructed out of massless spin s, s−1, ... ones leading to gauge invariant description of massive particle. Mainly we consider massive spin 3/2 supermultiplets in a flat d = 4 Minkowski space both without central charge for N = 1, 2, 3 as well as with central charge for N = 2, 4. Besides, we give two examples of massive N = 1 supermultiplets with spin 3/2 and 2 in AdS4 space.
Which field representations are allowed in interacting locally supersymmetric field theories
Abstract A free supersymmetric theory may appear in several forms with different field representations. We give a criterion for deciding which of these can be extended to locally supersymmetric interacting theories, along with two examples for which this criterion is not met and an explicit verification of the absence of consistent interactions for them.
