Three-point functions of chiral operators in D = 4, N = 4 SYM at large N

Abstract

We study all three-point functions of normalized chiral operators in D = 4, N = 4, U(N) supersymmetric Yang-Mills theory in the large N limit. We compute them for small 't Hooft coupling λ = g2Y MN ≪ 1 using free field theory and at strong coupling λ = g2Y MN ≫ 1 using the AdS/CFT correspondence. Surprisingly, we find the same answers in the two limits. We conjecture that at least for large N the exact answers are independent of λ.
