Nature of problem:
Generation of events according to multiparticle phase space, with high efficiency of the weight distribution.
The phase space volume for massless particles is expressed in a form which gives rise to a new event generator with 100% efficiency. For massive particles, a correction is applied which is exact and which progressively reduces the efficiency as the particle masses increase.
The submitted version of the program is dimensioned for a maximum of 100 outgoing particles, but can in principle be redimensioned to any number.
Compared with the traditional Raubold-Lynch generator, RAMBO is much more efficient when particle masses are small (sum of masses less than half of the total energy), especially for large numbers of outgoing particles.
Proportional to the number of events generated. See text.
