AdS5 vacua and holographic RG flows from 5D N=4 gauged supergravity

Abstract

We study five-dimensional $N=4$ gauged supergravity coupled to five vector multiplets with $SO(2{)}_D\times SO(3)\times SO(3)$ gauge group. There are four supersymmetric $Ad{S}_5$ vacua in the truncation to $SO(2{)}_{\text{diag}}$ invariant scalars. Two of these vacua preserve the full $N=4$ supersymmetry with $SO(2{)}_D\times SO(3)\times SO(3)$ and $SO(2{)}_D\times SO(3{)}_{\text{diag}}$ symmetries. These have an analogue in $N=4$ gauged supergravity with $SO(2)\times SO(3)\times SO(3)$ gauge group. The other two $Ad{S}_5$ vacua preserve only $N=2$ supersymmetry with $SO(2{)}_{\text{diag}}\times SO(3)$ and $SO(2{)}_{\text{diag}}$ symmetry. The former has an analogue in the previous study of $SO(2{)}_D\times SO(3)$ gauge group while the latter is a genuinely new $N=2$ $Ad{S}_5$ vacuum. These vacua are dual to $N=2$ and $N=1$ superconformal field theories (SCFTs) in four dimensions with different flavour symmetries. We give the full scalar mass spectra at all of the $Ad{S}_5$ critical points which provide information on conformal dimensions of the dual operators. Finally, we study holographic RG flows interpolating between these $Ad{S}_5$ vacua and find a new class of solutions. In addition to the RG flows from the trivial $SO(2{)}_D\times SO(3)\times SO(3)$ $N=4$ critical point, at the origin of the scalar manifold, to all the other critical points, there is a family of RG flows from the trivial $N=4$ critical point to the new $SO(2{)}_{\text{diag}}$ $N=2$ critical point that pass arbitrarily close to the $SO(2{)}_D\times SO(3{)}_{\text{diag}}$ $N=4$ critical point.
