Correlation functions in the Coulomb branch of N=4 super Yang-Mills theory from AdS-CFT correspondence -: art. no. 046009

We study SU(N)-->S[U(N/2)XU(N/2)] symmetry breaking in N=4 SYM via anti-de Sitter-conformal field theory correspondence. Two stacks of N/2 parallel D3 branes are separated by a distance 2d in the transverse directions. This leads to an interaction between different I-wave dilatonic Kaluza-Klein modes when expanded in S-5 harmonics. We calculate certain two-point correlation functions of the dual gauge theory in the decoupling limit d/alpha'much less than 1. Because of mode mixing, the diagonal correlation functions have 1/N conformal-like corrections as well as deformation terms. The off-diagonal correlators are also nonvanishing and their leading order is 1/N. We discuss briefly the spectrum of the glueball excitations.
