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…

Three-loop helicity amplitudes for four-quark scattering in massless QCD
Fabrizio Caola, Amlan Chakraborty, Giulio Gambuti +2
We compute the three-loop corrections to the helicity amplitudes for scattering in massless QCD. In the Lorentz decomposition of the scattering amplitude we…
