S = -1 baryons - an experimental review

This review sets out to compile a spectrum of the more probable strangeness -1 Baryons from the claims of the different partial wave analyses and the total cross-section and production experiments. For this purpose recently published and preliminary unpublished data in KN induced channels is reviewed and compared with predictions of various partial wave amplitudes. Results from a new partial wave analysis of the KN channel covering the range 1470 to 2170 MeV in the c.m. are presented. The spectrum of Ysup(*)s and the values for their decay amplitudes are compared with the QCD based quark model of Isgur and Karl. New experiments are suggested to help determine the KN, πLAMDA and πΣ partial wave amplitudes with greater certainty. (author)
