Generating heavy particles with energy and momentum conservation

Abstract
We propose a novel algorithm, called REGGAE, for the generation of momenta of a given sample of particle masses, evenly distributed in Lorentz-invariant phase space and obeying energy and momentum conservation. In comparison to other existing algorithms, REGGAE is designed for the use in multiparticle production in hadronic and nuclear collisions where many hadrons are produced and a large part of the available energy is stored in the form of their masses. The algorithm uses a loop simulating...

Title of program: REGGAE (REscatterig-after-Genbod GenerAtor of Events)
Catalogue Id: AEJR_v1_0

Nature of problem
The task is to generate momenta of a sample of particles with given masses which obey energy and momentum conservation. Generated samples should be evenly distributed in the available Lorentz invariant phase space.
