An SL(3,R) multiplet of 8-dimensional type II supergravity theories and the gauged supergravity inside

The so-called "massive 11-dimensional supergravity" theory gives, for one Killing vector, Romans' massive 10-dimensional supergravity in 10 dimensions, for two Killing vectors an Sl(2, R) multiplet of massive 9-dimensional supergravity theories that can be obtained by standard generalized dimensional reduction type IIB supergravity and has been shown to contain a gauged supergravity. We consider a straightforward generalization of this theory to three Killing vectors and a 3 x 3 symmetric mass matrix and show that it gives an Sl(3, R) multiplet of 8-dimensional supergravity theories that contain an SO(3) gauged supergravity which is, in some way, the dual to the one found by Salam and Sezgin by standard generalized dimensional reduction, (C) 2001 Published by Elsevier Science B.V.
