Pseudovector mesons, hybrids, and glueballs

We consider glueball- (hybrid) meson mixing for the low-lying four pseudovector states. The h 1 ′ (1380) decays dominantly to K * K with some presence in ρπ and ωη. The newly observed h 1 (1600) has a D- to S- wave width ratio to ωη which does not enable differentiation between a conventional and hybrid meson interpretation. We predict the decay pattern of the isopartner conventional or hybrid meson b 1 (1650). A notably narrow ss partner h 1 ′ (1810) is predicted.
