Possible ω Y(1S) Tetraquark Explanations for the χb0(2P)

The χb0(2P) is investigated using a first-order tetraquark model. An ω Y(1S) configuration is evaluated assuming weakly interacting ω and Y(1S) meson clusters. The χb0(2P) model yields a Jπ = 0+ value in agreement with data as well as 1+ and 2+ possible assignments. A mass of 10.3705 GeV/c2 is predicted by the model. This value is about 1.3% larger than the value suggested by the Belle Collaboration.
