Non-planar integrated correlator in SYM

arXiv:2404.18900 · doi:10.1103/PhysRevD.110.025003

Abstract

Integrated correlator of four superconformal stress-tensor primaries in super Yang-Mills (SYM) theory in the perturbative limit takes a remarkably simple form, where the -loop coefficient is given by a rational multiple of . In this letter, we extend the previous analysis of expressing the perturbative integrated correlator as a linear combination of periods of -graphs, graphical representations for loop integrands, to the non-planar sector at four loops. At this loop order, multiple zeta values make their first appearance when evaluating periods of non-planar -graphs, but cancel non-trivially in the weighted sum. The remaining single zeta value, along with the rational number prefactor, makes a perfect agreement with the prediction from supersymmmetric localisation.
