A Short Note on 2-Loop Box Functions
journal contribution
posted on 2023-05-16, 09:48 authored by Kreimer, DIt is shown that the two-loop four-point functions are similar in structure to the three-point two-loop functions for all mass cases and topologies. The result is derived by using a rotation to a (+, -, -, +) signature without spoiling analyticity properties.
