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