Class Summary
Class	Description
JetN2	JetN2 is an implementation of the longitudinally-invariant kT, anti-KT and Cambridge/Aachen clustering algorithms.
KTjet	Longitudinally-invariant kT, anti-KT and Cambridge/Aachen clustering algorithms (light-weight implementation).
Main
ParticleD	A class representing a jet or particle with pre-computed px,py,pz,e (double precision).
ParticleF	A class representing a jet or particle with pre-computed et, et2, phi, eta (float values).
SCJet	SCJet is an implementation of the longitudinally-invariant kT, anti-KT and Cambridge/Aachen clustering algorithms.

Package hephysics.jet Description

Java implementation of the longitudinally invariant kT, Cambridge/Aachen and anti-KT clustering algorithms using the recombination method.

JetN2 - a jet algorithm that uses N**2 geometrical approach, similar to C++ FastJet.
SCJet - a traditional N*3 algorithm
KTjet - uses pseudorapidity and float values. A fast light-weight implementation.

Note: Use JetN2 where possible. This algorithm has a speed similar to C++ FastJet.
