# Approximation formula and algol program of the Lorentz-invariant momentum-space integral for particles of equal masses

## Description

Title of program: LIMS Catalogue Id: AAUE_v1_0 Nature of problem In high-energy particle reactions the transition probability can be written as the product of some squared transition-matrix element and the volume of momentum space of the outgoing particles. The statistical hypothesis means putting this matrix element independent of the individual particles' momenta, so that the transition probability is proportional to some momentum space integral. This idea, with due modifications, has proved rather useful in describing particle production spectra and in pro ...
