Two-loop five-parton leading-colour finite remainders in the spinor-helicity formalism

A bstract We present all two-loop five-parton leading-colour finite remainders in the spinor-helicity formalism by analysing numerical evaluations of their known expressions terms Mandelstam invariants. Recasting them variables allows us to obtain which are more compact, faster evaluate, numerically stable and manifestly free from poles higher order than necessary. At same time, due better scaling our reconstruction strategy with complexity input, we required one magnitude fewer samples complete analytical were needed authors ref. [1], albeit using working precision. This places technique as an alternative finite-field single-numerator for future applications.
