Maxwell-Einstein Supergravity Theories Coupled to Tensor Multiplets

We study the general gaugings of N = 2 Maxwell-Einstein supergravity theories (MESGT) in five dimensions, extending and generalizing previous work. The global symmetries of these theories are of the form SU(2)R×G, where SU(2)R is the R-symmetry group of the N = 2 Poincaré superalgebra and G is the group of isometries of the scalar manifold that extend to symmetries of the full action. We first gauge a subgroup K of G by turning some of the vector fields into gauge fields of K while dualizing the remaining vector fields into tensor fields transforming in a non-trivial representation of K. Surprisingly, we find that the presence of tensor fields transforming non-trivially under the Yang-Mills gauge group leads to the introduction of a potential which does not admit an AdS ground state. Next we give the simultaneous gauging of the U(1)R subgroup of SU(2)R and a subgroup K of G in the presence of K-charged tensor multiplets. The potential introduced by the simultaneous gauging is the sum of the potentials introduced by gauging K and U(1)R separately. We present a list of possible gauge groups K and the corresponding representations of tensor fields. For the exceptional supergravity we find that one can gauge the SO∗(6) subgroup of the isometry group E6(−26) of the scalar manifold if one dualizes 12 of the vector fields to tensor fields just as in the gauged N = 8 supergravity. 1 Work supported in part by the National Science Foundation under Grant Number PHY-9802510.
