THE MONTE-CARLO PROGRAM KORALZ, VERSION 3.8, FOR THE LEPTON OR QUARK PAIR PRODUCTION AT LEP SLC ENERGIES

The Monte Carlo program for tau-pair production and decay applicable to the experiments in e+e- colliders in the Z resonance energy range is presented. The program includes initial-state bremsstrahlung corrections up to O(alpha-2) (with exclusive exponentiation), final-state O(alpha) bremsstrahlung and O(alpha) electroweak corrections. The following tau-decay modes can be generated: tau +/- --> nu-nu-eBAR +/-, nu-nu-mu-BAR +/-, nu-pi +/-, nu-rho +/-, nu-K1 +/-, nu-K* +/-, nu-a1 +/-, nu-4-pi +/-,0, nu-5-pi +/-,0, nu-6-pi +/-,0 including leading logarithmic radiative corrections in decays. The program can be also used for the generation of the final states different from tau+tau- pairs,i.e. is able to generate mu+mu-, nu-nu-BAR, uuBAR, ddBAR, ccBAR, ssBAR and bbBAR final states.
