The complete N=3 Kaluza-Klein spectrum of 11D supergravity on AdS4 x N010

We derive the invariant operators of the zero-form, the one-form, the two-form and the spinor from which the mass spectrum of Kaluza-Klein of eleven-dimensional supergravity on AdS(4) x N-010 can be derived by means (of harmonic analysis. We calculate their eigenvalues for all representations of SU(3) x SO(3). We show that the information contained in these operators is sufficient to reconstruct the complete N = 3 supersymmetry content of the compactified theory. We find the N = 3 massless graviton multiplet, the Betti multiplet and the SU(3) Killing vector multiplet. (C) 2000 Elsevier Science B.V. All rights reserved.
