A Monte Carlo generation method with importance sampling for high energy collisions of Hadrons

Title of program: GENIS Catalogue Id: AAUA_v1_0 Nature of problem In the theoretical analysis of hadron collisions at high energies the numerical evaluation of integrals over complete phase space is wasteful of computer time because experiment shows that only a small region of the integration domain is relevant for most physical purposes. This region is characterised by small values of the transverse momenta of the particles produced in the collision.
