【 摘 要 】

The KEDR experiment, which started in 2002, is dedicated to a study of c- and b-quarks and the two-photon physics at the e+e-collider VEPP-4M in the Budker INP. To analyze the 2γ data and estimate contribution of two-photon background events in the 1 data samples, the event generators e+e-→ e+e-+ hadrons, e+e-→ e+e-+ π+π-, and e+e-→ e+e-+ PS (PS - pseudoscalar meson) have been developed.
