Possible BB_ Tetraquark for the χb(2P) at 10.236 GeV/c2

The χb(2P) is investigated using a first-order tetraquark model assuming weakly interacting   meson clusters. The χb(2P) model yields a Jπ = 0+ value in agreement with other analysis that also suggests 1+ and 2+ possible assignments. A mass of 10.154 GeV/c2 is predicted by the model. This value is about 1.1% larger than the value suggested by the Brambilla et al. and the Belle Collaboration.
