Does the Sigma(1580)3/2^- resonance exist?
Precise new data for the reaction K-p->pi^0 Lambda are presented in the c.m. energy range 1565 to 1600 MeV. Our analysis of these data sheds new light on claims for the Sigma(1580) 3/2^- resonance, which (if it exists with the specified quantum numbers) must be an exotic baryon because of its very low mass. Our results show no evidence for this state.
