In the present paper we study S(N) → S(U (N/2) × U (N/2)) symmetry breaking in N = 4 SY M via AdS/CFT correspondence. We consider two stacks of N/2 parallel D3 branes separated by a distance 2 d. In this case there is mixing between the different l-wave dilatonic KK modes. We calculate certain the two point correlation functions in the dual gauge theory. Due to mode mixing, the diagonal correlation functions have 1/N conformal-like correction 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 exitations.
