Title: Propagators of light scalar mesons

Abstract

For the first time, as far as we know, in field theory are found explicit forms of propagators satisfying the Kaellen-Lehmann representation. To be exact, it is shown that scalar meson propagators, taking into account a virtual intermediate state contribution to the resonance self-energy, satisfy the Kaellen-Lehmann representation in the wide domain of coupling constants of the light scalar mesons with the two-particle states. It is proposed to use these propagators in routine fitting data about light scalar mesons to reveal physics underlying the light scalar mesons.
