Manuscript Title: KtJet: a C++ implementation of the Kt clustering algorithm.
Authors: J.M. Butterworth, J.P. Couchman, B.E. Cox, B.M. Waugh
Program title: KT++ 1.0
Catalogue identifier: ADRR_v1_0
Distribution format: tar.gz
Journal reference: Comput. Phys. Commun. 153(2003)85
Programming language: C++.
Operating system: Linux (Red Hat 7/SuSE 6).
RAM: 1.2M words
Keywords: Jet algorithms, Quantum chromodynamics, Elementary particle physics, Event reconstruction.
Classification: 11.9.

Nature of problem:
Cluster of hadrons in the final state of high energy particle collisions.

Solution method:
Pairwise recombination according to Kt related distance parameters.

Restrictions:
None.

Unusual features:
None.

Additional comments:
KtJet uses the HepLorentzVector class of the CLHEP package [1].

Running time:
Depends heavily on input data and choice of parameters. Increases as N^3 where N is the number of input objects.
