Nature of problem:
Generation of multiparticle events distributed randomly and uniformly in Lorentz-invariant phase space.
A new method for massive particles based on comparison with the exact integrals for zero-mass particles.
The program as distributed can handle up to 30 outgoing particles, but it is trivial to redimension it for a larger number.
It can be used to generate unit-weight events efficiently.
About a millisecond per event and per outgoing particle on a 25 Megaherz 80386 machine with a 80387 math coprocessor.
