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

Abstract A C++ implementation of the K_⊥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.
