On the spin-2 Kaluza-Klein spectrum of AdS4 x S2(B4)

Abstract

We perform a numerical study of the four-dimensional spin-2 Kaluza-Klein spectrum of supersymmetric AdS${}_4\times S^2({\mathcal{B}}_4)$ vacua and show that they do not exhibit scale separation. Our methods are generally applicable to similar problems where the compactification geometry is not known analytically, hence an analytic treatment of the spectrum of Kaluza-Klein masses is not available.
