  This report summarizes the most important results presented at the recent
conference held at the Yukawa Institute of Theoretical Physics in Kyoto,
devoted to the recently confirmed light sigma resonance. Remarkably, all
speakers at this meeting took the light sigma for granted and many mass and
width estimations near 500 MeV were presented. We emphasize that if the light
and broad sigma is accepted as a true resonance it explains many basic problems
of low energy hadronic physics in a simple way, especially if the linear sigma
model is used as an approximate effective low energy theory.
