AdS/CFT duality and the Higgs branch of N=2 SYM

We construct the AdS description of the Higgs branch of the finite N = 2 Sp(N) gauge theory with one antisymmetric hypermultiplet and four fundamental hypermultiplets. Holography, combined with the non-renormalization of the metric on the Higgs branch, leads to novel constraints on unknown terms in the non-abelian Dirac-Bom-Infeld action. These terms include non-minimal couplings of D-branes to bulk supergravity fields. (c) 2005 WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim.
