The nonplanar cusp and collinear anomalous dimension at four loops in $\mathcal{N}=4$ SYM theory

Rutger H. Boels, Tobias Huber, Gang Yang

We present numerical results for the nonplanar lightlike cusp and collinear anomalous dimension at four loops in $\mathcal{N}=4$ SYM theory, which we infer from a calculation of…
