Proposed Tbb Tetraquark at 10.5765 GeV/c2

The proposed Tbb tetraquark at 10.5765 GeV/c2 is investigated using a first-order model assuming weakly interacting   plus   meson clusters. The Tbb model yields a Jπ = 1+ value in agreement with other analysis, and also suggests 0+ and 2+ possible assignments. Depending on the assumed spin and parity of each meson cluster, the model yields mass values in the range of 10.150 – 10.238 GeV/c2. These values are within about 4% of the proposed lattice QCD value.
