A note on three-point functions of unprotected operators
Abstract
Abstract Given the recent progress in computing three-point functions in N $$ \mathcal{N} $$ = 4 SYM via integrability, I provide here a novel direct calculation of some structure constants at weak coupling. The main focus is on correlators involving more than one unprotected operator, at two-loop order in the perturbative expansion.
