The higher-dimensional origin of five-dimensional N $$ \mathcal{N} $$ = 2 gauged supergravities

Abstract

Abstract Using exceptional generalised geometry, we classify which five-dimensional N $$ \mathcal{N} $$ = 2 gauged supergravities can arise as a consistent truncation of 10-/11-dimensional supergravity. Exceptional generalised geometry turns the classification into an algebraic problem of finding subgroups G S ⊂ USp(8) ⊂ E6(6) that preserve exactly two spinors. Moreover, the intrinsic torsion of the G S structure must contain only constant singlets under G S , and these, in turn, determine the gauging of the five-dimensional theory. The resulting five-dimensional theories are strongly constrained: their scalar manifolds are necessarily symmetric spaces and only a small number of matter multiplets can be kept, which we completely enumerate. We also determine the largest reductive and compact gaugings that can arise from consistent truncations.
