Abstract AAn extended version of the Monte Carlo program GALUGA is presented for the computation of two-photon production in e^+ e^-collisions. Functions implemented for the five γ*γ* structure functions now include several ansätze of the total hadronic cross section based on the BFKL Pomeron and various Regge-like models. In addition, structure functions for resonance formation are included with full dependence on the two-photon virtualities Q^2 _1and Q^2 _2as given in the constituent-quark mode... Title of program: GALUGA Catalogue Id: ADHE_v1_0 Nature of Problem Hadronic two-photon reactions in a new energy domain are becoming accessible with LEP2. Unlike purely electroweak processes, hadronic processes contain dominant non-perturbative components parametrized by suitable structure functions, which are functions of the two-photon invariant mass W and the photon virtualities Q1 and Q2. It is hence advantageous to have a Monte Carlo program that can generate events with the possibility to keep W and, optionally, Qi at fixed, user-defined values. Moreover, ...
