Welcome to NJet project wiki

NJet is a library for multi-parton one-loop matrix elements in massless QCD. NJet is based on the generalized unitarity program NGluon and uses QCDLoop/FF for scalar intergrals and libqd for extended precision arithmetic.

  • 05.05.2014 NJet version 2.0.0 with more processes has been released and is now available in the downloads section. It provides jets, W+jets, Z+jets, A+jets, AA+jets virtual matrix elements via BLHA2 interface. As well as leading/subleading colour, desymmetrized amplitudes, colour and spin-correlated trees. It also features significant speed improvement for 2- and 3-jet processes by utilizing analytic expressions for a selection of amplitudes.
