Neutral B-meson decay and the search for hybrid mesons

We discuss the possibility that the decay of the neutral B mesons via a non-spectator mechanism might have a significant branching fraction into $\text{(}\text{q}\text{q}\text{g}\text{)}$ states. The lightest such hybrid mesons would be recognizable as narroe state of mass 1.6 ± 0.4$\text{GeV}\text{c}{}^2$ decaying predominantly into hadrons containing strange quarks.
