From the divergent part of the latter the cusp and collinear anomalous dimensions are extracted. Results are also presented for the finite contribution. We briefly describe our method to compute all planar master integrals at four-loop order.","authors_text":"Alexander V. Smirnov, Johannes M. Henn, Matthias Steinhauser, Vladimir A.
