Testing the AdS / CFT correspondence beyond large N

According to the AdS/CFT correspondence, the d = 4, N = 4 SU(N) super Yang-Mills theory is dual to the type IIB string theory compactified on AdS5 × S. Most of the tests performed so far are confined to the leading order at large N or equivalently string tree-level. To probe the correspondence beyond this leading order and obtain 1 N2 corrections is… CONTINUE READING
