Abstract

Evidence is presented for two J^P=2^- strange mesons; one at ∼ 1.77 GeV/c² and the other at ∼ 1.82 GeV/c². These states have been observed in a partial wave analysis of the Kω system in the reaction K^-p→K^-π⁺π^-π⁰p where the strange mesons decay into K^-ω and the ω then decays to π⁺π^-π⁰. The data set contains ∼ 10⁵ Kωp events at 11 GeV/c taken by the LASS spectrometer at SLAC.
