FastJet – software for jet finding in pp and e+e− collisions

FastJet is a software package for jet finding in pp and e+e collisions.

FastJet is a C++ package that provides a broad range of jet finding and analysis tools. It includes efficient native implementations of all widely used 2->1 sequential recombination jet algorithms for pp and e+e collisions, as well as access to 3rd party jet algorithms through a plugin mechanism, including all currently used cone algorithms.

FastJet also provides means to facilitate the manipulation of jet substructure, including some common boosted heavy-object taggers, as well as tools for estimation of pileup and underlying-event noise levels, determination of jet areas and subtraction or suppression of noise in jets.

Features include:

  • Native jet algorithms:
    • Longitudinally invariant kt jet algorithm.
    • Cambridge/Aachen jet algorithm.
    • Anti-kt jet algorithm.
    • Generalised kt jet algorithm.
    • Generalised kt algorithm for e+e collisions.
    • kt algorithm for e+e collisions.
  • Plugin jet algorithms.
