Pentagon Functions for One-Mass Planar Scattering Amplitudes
Dmitry Chicherin, Vasily Sotnikov, Simone Zoia
We present analytic results for all planar two-loop Feynman integrals contributing to five-particle scattering amplitudes with one external massive leg. We express the integrals in…
Virtual QCD corrections to gluon-initiated diphoton plus jet production at hadron colliders
Simon Badger, Christian Brønnum-Hansen, Dmitry Chicherin +7
We present an analytic computation of the gluon-initiated contribution to diphoton plus jet production at hadron colliders up to two loops in QCD. We reconstruct the analytic form…
Cluster algebras for Feynman integrals
Dmitry Chicherin, Johannes M. Henn, Georgios Papathanasiou
We initiate the study of cluster algebras in Feynman integrals in dimensional regularization. We provide evidence that four-point Feynman integrals with one off-shell leg are descr…
