Integrand Analysis, Leading Singularities and Canonical Bases beyond Polylogarithms
Felix Forner, Cesare Carlo Mella, Christoph Nega +2
In this paper, we elaborate on the connection between leading singularities and canonical bases of Feynman integrals beyond polylogarithms. We start by discussing a notion of leadi…

Graded transcendental functions: an application to four-point amplitudes with one off-shell leg
Thomas Gehrmann, Johannes Henn, Petr JakubÄÃk +5
Several recent works have demonstrated the powerful algebraic simplifications that can be achieved for scattering amplitudes through a systematic grading of transcendental quantiti…
