Low energy parameters of the K K-bar and ππ scalar-isoscalar interactions

  • 1. Institute of Nuclear Physics, Cracow (Poland)

Description

Threshold expansions of the ππ and K K-bar spin 0 and isospin 0 scattering amplitudes are performed. Scattering lengths, effective ranges and so-called volume parameters are evaluated. Good agreement with the existing experimental data for the ππ scalar-isoscalar amplitude is found. An importance of future accurate measurements of the K K-bar threshold parameters is stressed. New data are needed to understand the basic features of the scalar mesons. (author). 31 refs, 3 tabs
