D. Fabbri et al., Osp(N vertical bar 4) supermultiplets as conformal superfields on partial derivative AdS(4) and the generic form of N = 2, d = 3 gauge theories, CLASS QUANT, 17(1), 2000, pp. 55-92
In this paper we fill a necessary gap in order to realize an explicit compa
rison between the Kaluza-Klein spectra of supergravity compactified on AdS(
4) x X-7 and superconformal field theories living on the worldvolume of M2-
branes. On the algebraic side we consider the superalgebra Osp(N/4) and we
study the double interpretation of its unitary irreducible representations
either as supermultiplets of particle states in the bulk or as a conformal
superfield on the boundary. On the Lagrangian field theory side we construc
t, using rheonomy rather than superfield techniques, the generic form of an
N = 2, d = 3 gauge theory. Indeed, the superconformal multiplets are suppo
sed to be composite operators in a suitable gauge theory.
