We compute the integrands of five-, six-, and seven-point correlation functions of twenty-prime operators with general polarizations at the two-loop order in $\mathcal{N}=4$ super Yang-Mills theory. In addition, we compute the integrand of the five-p

Abstract We explain how the ’t Hooft expansion of correlators of half-BPS operators can be resummed in a large-charge limit in N $$ \mathcal{N} $$ = 4 super Yang-Mills theory. The full correlator in the limit is given by a non-trivial function of t

In a previous work, we proposed an integrability setup for computing non-planar corrections to correlation functions in $\mathcal{N}=4$ super Yang-Mills theory at any value of the coupling constant. The procedure consists of drawing all possible tree

Four-Point Functions with a Twist

We study the OPE of correlation functions of local operators in planar N=4 super Yang-Mills theory. The considered operators have an explicit spacetime dependence that is defined by twisting the translation generators with certain R-symmetry generato

We study Yangian-invariant deformations of scattering amplitudes in 4d N=4 super Yang-Mills theory and 3d N=6 Aharony-Bergman-Jafferis-Maldacena (ABJM) theory. In particular
