Description

If the exotic baryon Θ+(1540) is a correlated ududs with JP=(1+/2), then there should exist an exotic meson θ+ with strangeness +2, JP=1-, mass ∼1.6 GeV, decaying to K+K0 with width O(10-100) MeV. The π1(1400;1600) may be broad members of 10±10 in such a picture, and it is possible that vector mesons in the 1.4-1.7 GeV mass range are related to this multiplet. We suggest that dynamical correlations may limit the spectrum of JP(C) such that the 1-(±) states are isolated
