We study four-dimensional gauged supergravity coupled to six vector multiplets with semisimple gauge groups , and . All of these gauge groups are dyonically embedded in the global symmetry group SO(6, 6) via its maximal subgroup . For gauge group, there are four supersymmetric vacua with , , and symmetries, respectively. These vacua correspond to SCFTs in three dimensions with SO(4) R-symmetry and different flavor symmetries. We explicitly compute the full scalar mass spectra at all these vacua. Holographic RG flows interpolating between these conformal fixed points are also given. The solutions describe supersymmetric deformations of SCFTs by relevant operators of dimensions . A number of these solutions can be found analytically although some of them can only be obtained numerically. These results provide a rich and novel class of fixed points in three-dimensional Chern–Simons-Matter theories and possible RG flows between them in the framework of gauged supergravity in four dimensions. Similar studies are carried out for non-compact gauge groups, but the gauge group exhibits a much richer structure.
