On supergravity duals of N=1 SCFT in four dimensions

We present D3-brane solutions in type IIB string theory which preserve 1/8 of supersymmetry. Their transverse space is Ricci-flat but not flat and in fact a cone over an appropriate five dimensional Einstein space X/sup 5/. Supersymmetry is preserved if X/sup 5/ is a U(1) bundle over a Kahler-Einste...

Sumario:We present D3-brane solutions in type IIB string theory which preserve 1/8 of supersymmetry. Their transverse space is Ricci-flat but not flat and in fact a cone over an appropriate five dimensional Einstein space X/sup 5/. Supersymmetry is preserved if X/sup 5/ is a U(1) bundle over a Kahler-Einstein complex surface S with positive first Chern class c/sub 1/>0. Their near-horizon geometry is described by AdS/sup 5/*X/sup 5/ and they should be the supergravity duals of certain four-dimensional superconformal field theories. (38 refs).
