Description

This program has been imported from the CPC Program Library held at Queen's University Belfast (1969-2018) 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. Title of program: CAMORRA Catalogue Id: AEHN_v1_0 Nature of problem Current recursive matrix element computation programs are confined to standard model amplitudes, whereas many new physics signatures and backgrounds at hadron colliders are associated with multi-parton final states. Versions of this program held in the CPC repository in Mendeley Data AEHN_v1_0; CAMORRA; 10.1016/j.cpc.2010.09.020
