Elliptic Leading Singularities and Canonical Integrands

Author(s): E. Chaubey and V. Sotnikov In the well-studied genus zero case, bases of d log integrands with integer leading singularities define Feynman integrals that automatically satisfy differential equations in canonical form. Such integrand bases can be constructed without input from the differential equations and without explicit i… [Phys. Rev. Lett. 135, 101903] Published Thu Sep 04, 2025
