Abstract
We study the quark-antiquark interaction in the large-N limit of the superc onformal field theory on D3-branes at a Calabi-Yau conical singularity. We compute the Wilson loop in the AdS(5) x T-11 supergravity background for th e SU(2N) x SU(2N) theory. We also calculate the Wilson loop for the Higgs p hase where the gauge group is broken to SU(N) x SU(N) x SUD(N). This corres ponds to a two center configuration with some of the branes at the singular ity and the rest of them at a smooth point. The calculation exhibits the ex pected Coulomb dependence for the interaction. The angular distribution of the BPS states is different than the one for a spherical horizon.
