The on-shell expansion: from Landau equations to the Newton polytope
Einan Gardi, Franz Herzog, Stephen Jones +2
We study the application of the method of regions to Feynman integrals with massless propagators contributing to off-shell Green's functions in Minkowski spacetime (with non-except…

The Hopf algebra structure of the -operation
Robert Beekveldt, Michael Borinsky, Franz Herzog
We give a Hopf-algebraic formulation of the -operation, which is a canonical way to render UV and IR divergent Euclidean Feynman diagrams finite. Our analysis uncovers a close…

The R*-operation for Feynman graphs with generic numerators
Franz Herzog, Ben Ruijl
The R*-operation by Chetyrkin, Tkachov, and Smirnov is a generalisation of the BPHZ R-operation, which subtracts both ultraviolet and infrared divergences of euclidean Feynman grap…
