Two-photon mechanism of production of scalar mesons at colliders

Abstract

The cross sections of the scalar meson $f_0(980)$, $a_0(980)$ and $\sigma (600)$ production in collision of electron and positron beams were calculated. The two-photon decays of the scalar mesons, obtained in the framework of the Nambu-Jona-Lasinio model, were used. The quark and meson loops were taken into account.
