Gauged/massive supergravities in diverse dimensions

Abstract

We show how massive/gauged maximal supergravities in 11− n dimensions with SO( n− l, l) gauge groups (and other non-semisimple subgroups of Sl(n, R) ) can be systematically obtained by dimensional reduction of “massive 11-dimensional supergravity”. This series of massive/gauged supergravities includes, for instance, Romans' massive N=2 A, d=10 supergravity for n=1, N=2, d=9 SO(2) and SO(1,1) gauged supergravities for n=2, and N=8, d=5 SO(6− l, l) gauged supergravity. In all cases, higher p-form fields get masses through the Stückelberg mechanism which is an alternative to self-duality in odd dimensions.
