We report the first observation of the + decay mode of the 0 (1690), confirming the existence of this resonance. The 0 (1690) were produced by of 345 GeV=c mean momentum in copper and carbon targets. The mass and width are close to those observed earlier for the (1690) in the K decay channel. The product of inclusive production cross section and branching ratio is given relative to that of the 0 (1530).
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
