| contents | We present a comprehensive two-loop computation of correlation functions involving two maximal giant gravitons and two arbitrary $R$-charge single-trace half-BPS operators in $\mathcal{N}=4$ Super-Yang-Mills theory. By combining the partially-contracted giant graviton (PCGG) method with the $\mathcal{N}=2$ harmonic superspace formalism, we achieve significant simplifications in perturbative calculations. The resulting correlation functions encode rich CFT data, from which we derive sum rules for the OPE coefficients. These sum rules are in perfect agreement with integrability predictions. Furthermore, at the integrand level, we find a hidden higher dimensional symmetry present at both one- and two-loop orders. This symmetry was discovered recently at strong coupling, which generalizes its counterpart in correlation functions of single-trace operators. |
