Abstract

We study four-dimensional gauged supergravity with gauge group in the presence of symplectic deformations. There are in general four electric-magnetic phases corresponding to each factor, but two phases of the factors embedded in the R-symmetry are fixed. One phase can be set to zero by transformations. The second one gives equivalent theories for any non-vanishing values and can be set to resulting in gauged supergravities that admit supersymmetric vacua. The remaining two phases are truely deformation parameters leading to different gauged supergravities. As in the -deformed maximal gauged supergravity, the cosmological constant and scalar masses of the vacuum at the origin of the scalar manifold with symmetry do not depend on the electric-magnetic phases. We find holographic RG flow solutions between critical points with and or symmetries. We also give and RG flows from these critical points to various non-conformal phases. However, contrary to the -deformed gauged supergravity, there exist non-trivial supersymmetric critical points only for particular values of the deformation parameters within the scalar sectors under consideration.
