Two-photon mechanism of production of scalar mesons at colliders

TL;DR

This paper calculates the production cross sections of scalar mesons in electron-positron collisions via two-photon processes using the Nambu-Jona-Lasinio model, including quark and meson loop effects.

Contribution

It introduces a detailed calculation of scalar meson production cross sections at colliders using the NJL model with quark and meson loop contributions.

Findings

Calculated cross sections for $f_0(980)$, $a_0(980)$, and $\sigma(600)$ production.

Included two-photon decay mechanisms within the NJL model.

Accounted for quark and meson loop effects in the calculations.

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.
