TL;DR

This paper introduces GGRESRC, a Monte Carlo event generator designed to simulate two-photon processes producing pseudoscalar resonances in e+e- collisions, with detailed radiative correction features for single-tag events.

Contribution

The paper presents a new Monte Carlo generator specifically optimized for simulating two-photon pseudoscalar resonance production with radiative corrections in single-tag mode.

Findings

Efficient simulation of e+e- to e+e- R events with R being pseudoscalar resonances.

Inclusion of radiative corrections for accurate event modeling.

Applicability to various pseudoscalar mesons like b0, e9, e9', e9_c, and e9_b.

Abstract

The Monte Carlo event generator GGRESRC is described. The generator is developed for simulation of events of the two-photon process e^+e^- --> e^+e^- R, where R is a pseudoscalar resonance, \pi^0, \eta, \eta', \eta_c, or \eta_b. The program is optimized for generation of two-photon events in the single-tag mode. For single-tag events, radiative correction simulation is implemented in the generator including photon emission from the initial and final states.
