All Five-point Kaluza-Klein Correlators and Hidden 8d Symmetry in $\mathrm{A}\mathrm{d}{\mathrm{S}}_5\times {\mathrm{S}}^3$

We systematically compute five-point correlators of chiral primary operators with arbitrary Kaluza-Klein charges at tree-level in ${\mathrm{A}\mathrm{d}\mathrm{S}}_5\times {\mathrm{S}}^3$, and obtain a unified formula. This result serves as the first concrete confirmation for the existence of the hidden eight-dimensional symmetries at the level of five points.
