Generalized Cuts of Feynman Integrals in Parameter Space
Generalized Cuts of Feynman Integrals in Parameter Space
We propose a construction of generalized cuts of Feynman integrals as an operation on the domain of the Feynman parametric integral. A set of on-shell conditions removes the corresponding boundary components of the integration domain, in favor of including a boundary component from the second Symanzik polynomial. Hence integration domains …
