Dispersion relations in Kbar N - pi Y coupled channel analyses
Paolo M. Gensini, Rafael Hurtado, Galileo Violini
Abstract
Rapidly convergent, unsubtracted dispersion relations have been used to test coupled channel analyses of low-energy S = -1 meson-baryon pi Y --> pi Y' channels. We conclude that the low-energy S = -1 meson-baryon sector is less well known than currently believed, and that it deserves more accurate experiments and analyses.
