Abstract
Evidence is presented for two J(P) = 2- strange mesons; one at - 1.77 GeV/C2 and the other at approximately 1.82 GeV/c2. These states have b een observed in a partial wave analysis of the Komega system in the re action K-p-->K-pi+pi-pi0p where the strange mesons decay into K-omega and the omega then decays to pi+pi-pi0. The data set contains approxim ately 10(5) Komegap events at 11 GeV/c taken by the LASS spectrometer at SLAC.
