Gravity duals of 5D N=2 SYM from F(4) gauged supergravity

Abstract

We study gravity duals of the minimal $N=2$ super Yang-Mills (SYM) gauge theories in five dimensions using the matter coupled $F(4)$ gauged supergravity in six dimensions. The $F(4)$ gauged supergravity coupled to $n$ vector multiplets contains $4n+1$ scalar fields, parametrized by $\mathbb{R}^+\times SO(4,n)/SO(4)\times SO(n)$ coset manifold. Maximally supersymmetric vacua of the gauged supergravity with $SU(2)\times G$ gauge group, with $G$ being an $n$-dimensional subgroup of $SO(n)$, correspond to five dimensional superconformal field theories (SCFTs) with $SU(2)_R$ R-symmetry and $G$ global symmetry. Deformations of the UV SCFTs for $G=SU(2)$ and $G=U(2)\sim SU(2)\times U(1)$ symmetries that lead to non-conformal $N=2$ SYM with various unbroken global symmetries are studied holographically.
