Kaluza-Klein fermion mass matrices from Exceptional Field Theory and $N=1$ spectra

Using Exceptional Field Theory, the infinite-dimensional mass matrices for the gravitino and spin-1/2 Kaluza-Klein perturbations above a class of anti-de Sitter solutions of M-theory and massive type IIA string theory with topologically-spherical internal spaces can be determined. These mass matrices can be employed to compute the spectrum of Kaluza-Klein fermions about some solutions in this class with internal symmetry groups containing $SU(3)$. Combining these results with previously known bosonic sectors of the spectra, I will present the complete spectra about some $N=1$ and some non-supersymmetric solutions in this class, together with certain generic features they are shown to enjoy.
