The complete N=3 Kaluza–Klein spectrum of 11D supergravity on AdS4×N010 Original Research Article

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 AdS4×N010 can be derived by means of harmonic analysis. We calculate their eigenvalues for all representations of SU(3)×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.
