Study of leading strange meson resonances and spinorbit splittings in K()p yields K()pi(+)n at 11 GeV/c
Abstract
The results from a high statistics study of pi elastic scattering in the reaction K()p proceeds to K() pi(+)n are presented. By selecting the very forward produced K() pi(+) events, a sample consisting of data for the K pi proceeds to K pi elastic scattering reaction was extracted. The angular distribution for this mesonmeson scattering is studied by use of both a spherical harmonic moments analysis and a partialwave analysis (PWA). Evidence for spin 4 K resonance with a mass of 2080 MeV and a width of about 225 MeV is presented. The results from the PWA confirm the existence of a 0(+) kappa (1490) and propose the existence of a second scalar meson resonance, the 0(+) kappa' (1900). Structure in the P wave amplitude indicates resonance behavior in the mass region near 1700 MeV. In two of the four ambiguous solutions for the mass region above 1800 MeV, there is strong evidence for another P wave resonant structure near 2100 MeV. The observed strange meson resonances are found to have a natural interpretation in terms of states predicted by the quark model.
