All Five-point Kaluza-Klein Correlators and Hidden 8d Symmetry in $\rm AdS_5\times S^3$

Abstract: We systematically compute five-point correlators of chiral primary operators with arbitrary Kaluza-Klein charges at tree-level in $\mathrm{AdS}_5\times\mathrm{S}^3$, 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.
