Description
We study the main properties of N=4 SYM theory at a special point on the Coulomb branch, which corresponds to a U(N) to U(N-1) x U(1) symmetry breaking pattern. We investigate several general questions, using this theory as a toy model: renormalization of operators and one-point functions, convergence of the OPE, and constraints on OPE data. Moreover, in the protected sector, we check the holographic prescription by computing one-point functions at strong coupling and matching them with the perturbative calculation.
