Nonplanar Cusp and Transcendental Anomalous Dimension at Four Loops in $\mathcal{N}$=4 Supersymmetric Yang-Mills Theory

We compute the nonplanar contribution to the universal anomalous dimension of the SU(4)-singlet twist-two operators in $\mathcal{N}$=4 supersymmetric Yang-Mills theory at four loops through Lorentz spin 18. From this, we numerically evaluate the nonplanar contribution to the four-loop lightlike cusp anomalous dimension and derive the transcendental $ζ_3$ and $ζ_5$ parts of the universal anomalous dimension for arbitrary Lorentz spin in analytic form. As for the lightlike cusp anomalous dimension and the $ζ_5$ part of the universal anomalous dimension, we confirm previous results
