Abstract
An analysis is presented of ρπ and ωππ systems ine + e − annihilation. Definite evidence is obtained for two ω′ states at masses of 1.39 and 1.59 GeV. Incorporating these states in an analysis of the corresponding channels in diffractive photoproduction indicates the presence of a new process in isoscalar diffractive photoproduction which is not present in the isovector case. The possible relationship to the anomalous ratio of the rates of ψ′ andJ/ψ decay to ρπ is raised: both point to the presence of one or moreJ pc=1−− glueball states between 2 and 3 GeV.
