TREPS: A Monte-Carlo Event Generator for Two-photon Processes at $e^{+}{e}^{-}$ Colliders using an Equivalent Photon Approximation

Abstract

A description and the use of an event-generator code for two-photon processes at e+e- colliders, TREPS, are presented. This program uses an equivalent photon approximation in which the virtuality of photons is taken into account. It is applicable to various processes by specifying a combination of final-state particles and the angular distributions among them. A comparison of the results with those from other programs is also given.
