KtJet:: A C++ implementation of the K⊥ clustering algorithm

A C++ implementation of the L(perpendicular to) jet algorithm for high energy particle collisions is presented. The time performance of this implementation is superior to the widely used Fortran implementation. Identical algorithmic functionality is provided, with a clean and intuitive user interface and additional recombination schemes. A short description of the algorithm and examples of its use are given. (C) 2003 Elsevier Science B.V. All rights reserved.
