Implications of a JPC exotic
Abstract
Recent experimental data from BNL on the isovector JPC =1-+ exotic at 1.6 GeV in π indicate the existence of a non-quarkonium state consistent with lattice gauge theory predictions. We discuss how further experiments can strengthen this conclusion. We show that the π, η'π and ηπ couplings of this state qualitatively support the hypothesis that it is a hybrid meson, although other interpretations cannot be eliminated.
