Abstract

In 1982 Fermilab experiment E623 took data in a search for high-mass boson resonances which decay into one or two ɸ mesons produced in 400 GeV/c proton-nuclei interactions. A hardware trigger selected 3.6 million events with identified K⁺K⁻ pairs. Here I report my study of events with ɸKπ in the final state and present the first evidence for K°*(2060) decaying into ɸKπ and ɸK°*(890).
