FastJet 2.4.1 user manual

FastJet provides fast (N lnN,N 2) implementations of the longitudinally invariant kt, antikt and Cambridge/Aachen jet algorithms for pp collisions, based in part on tools and methods from the Computational Geometry community, as well as a native implementation of the e + e − kt algorithm. Further jet algorithms, including most of the other commonly used pp and e + e − algorithms, can be accessed from the FastJet interface using a plugin mechanism. FastJet also provides ways of determining jet areas.
