new results from computing planar and non-planar three-loop integrals for Higgs plus jet process — •Jungwon Lim — Max Planck Institute for Physics, Munich, Germany

We present new results for Feynman integrals relevant to Higgs plus jet production at three loops, including first results for a non-planar class of integrals. The results are expressed in terms of generalized polylogarithms up to transcendental weight six. We also provide the full canonical differential equations, which allows us to make structural observations on the answer. In particular, find a counterexample to previously conjectured adjacency relations, for a planar integral of the tennis court type. Moreover, for a non-planar triple ladder diagram, we find two novel alphabet letters. This information may be useful for future bootstrap approaches.
