Experimental evidence for the optimal states in kaon-nucleon scattering

In this paper an optimal state analysis of kaon-nucleon elastic scattering data is presented. It is shown that the optimal state prediction are experimentally satisfied to a surprising accuracy even for a single optimal state description of kaon-nucleon elastic scattering for laboratory momentum higher than 3 GeV/c. The optimal state analysis as an important alternative to the phase shift analysis is presented. (Author)
