Two-photon mechanism of production of scalar mesons at colliders
Abstract
The cross sections of the scalar meson f0(980), a0(980) and σ(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.
