GaGaRes: A Monte Carlo generator for resonance production in two-photon physics
F. A. Berends, R. van Gulik
Abstract
In this paper a Monte Carlo generator, GaGaRes, is presented which can be used to describe two-photon resonance production in e+e- collisions. The program can generate the five lowest-lying C=+1 meson states of any qq combination together with the outgoing electron and positron. The dependence on the photon virtualities Q12 and Q22 is fully taken into account. The program also generates the density matrices of the resonance, which form an essential tool in the description of the decay of the resonances. Furthermore, the program is applicable for all tagging conditions.
