The NJet code is currently available for the evaluation of tree-level and one-loop amplitudes. Development is ongoing and we hope to add some support for two-loop amplitudes very soon!
n3jet is a neural network interface to amplitudes in NJet.
Our new two-loop amplitude methods have been developed alongside Tiziano Peraro’s FiniteFlow code which supports the finite field arithmetic we use to side step traditional bottlenecks.
