Towards numerical two-loop integrand reduction
Giuseppe Bevilacqua, Dhimiter Canko, Costas Papadopoulos +1
We present a method for the integrand-level reduction of two-loop helicity amplitudes in both and dimensions. The amplitude is expressed in terms of a set of Feynman…

Two-loop Feynman integrals for leading colour production at hadron colliders
Matteo Becchetti, Dhimiter Canko, Vsevolod Chestnov +3
We compute a complete set of the two-loop Feynman integrals that are required for the next-to-next-to-leading order QCD corrections to on-shell top-pair production in association w…
