Holographic duals of a family of = 1* fixed points

We construct a family of warped AdS5 compactifications of IIB supergravity that are the holographic duals of the complete set of = 1* fixed points of a 2 quiver gauge theory. This family interpolates between the T1,1 compactification with no three-form flux and the 2 orbifold of the Pilch-Warner geometry which contains three-form flux. This family of solutions is constructed by making the most general Ansatz allowed by the symmetries of the field theory. We use Killing spinor methods because the symmetries impose two simple projection conditions on the Killing spinors, and these greatly reduce the problem. We see that generic interpolating solution has a nontrivial dilaton in the internal five-manifold. We calculate the central charge of the gauge theories from the supergravity backgrounds and find that it is (27/32) of the parent = 2, quiver gauge theory. We believe that the projection conditions that we derived here will be useful for a much larger class of = 1 holographic RG-flows.
