Gauged/massive supergravities in diverse dimensions Original Research Article

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, Romansʹ massive N=2A, 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.
