We report a new result for the NfβCF3β contribution to the four-loop
anomalous dimensions of non-singlet, twist-two operators in Quantum
Chromodynamics. This result is obtained through computations of off-shell
operator matrix elements. Employing integration-by-parts reductions and
differential equations with respect to a tracing parameter allowed us to derive
analytic results valid for arbitrary Mellin moment n.Comment: 13 pages, 1 figure, ancillary file with resul
