5d quivers and their AdS(6) duals

Understand

We consider an infinite class of 5d supersymmetric gauge theories involving products of symplectic and unitary groups that arise from D4-branes at orbifold singularities in Type I' string theory.

• The theories are argued to be dual to warped AdS(6)x S4/Zn backgrounds in massive Type IIA supergravity.
• In particular, this demonstrates the existence of supersymmetric 5d fixed points of quiver type.
• We analyze the spectrum of gauge fields and charged states in the supergravity dual, and find a precise agreement with the symmetries and charged operators in the quiver theories.
