CAMORRA: a C++ library for recursive computation of particle scattering amplitudes
arXiv:1006.5614 · doi:10.1016/j.cpc.2010.09.020
Abstract
We present a new Monte Carlo tool that computes full tree-level matrix elements in high-energy physics. The program accepts user-defined models and has no restrictions on the process multiplicity. To achieve acceptable performance, CAMORRA evaluates the matrix elements in a recursive way by combining off-shell currents. Furthermore, CAMORRA can be used to compute amplitudes involving continuous color and helicity final states.
