Notes on off-shell conformal integrals and correlation functions at five points (2512.21947v1)

Abstract: We study five-point off-shell conformal integrals and associated half-BPS correlation functions at the two-loop order in the 't Hooft coupling expansion in maximal supersymmetric Yang-Mills theory. We construct a basis of uniform transcendental, pure integrals, comprising six distinct topologies, through the method of diagonalizing leading singularities under the constraints of conformal invariance, which serve as basis integrals for conformally-symmetric observables at five points and two loops. By employing different conformal frame fixing choices, this integral basis can be mapped onto known two-loop four-massive-particle Feynman integral families. Subsequently, their integrated results are computed using the method of canonical differential equations and integration-by-parts reduction. We present for the first time the integrated results for the two-loop five-point half-BPS correlators, encompassing both maximal and non-maximal sectors, at symbol level.
