Could Yb(10890) be the P-wave [bq][(b)over-bar(q)over-bar] tetraquark state?

Assuming Y-b(10890) as a P-wave bq-scalar-diquark (b) over bar(q) over bar -scalar-antidiquark tetraquark state, the mass of Y-b(10890) is computed in the framework of QCD sum rule method. Technically, contributions of operators up to dimension six are included in the operator product expansion (OPE). The numerical result 10.88 +/- 0.13 GeV for Y-b(10890) agrees well with the experimental value, which favors the P-wave [bq][(b) over bar(q) over bar] tetraquark configuration for Y-b(10890). In the same picture, the mass of Y (4360) is calculated and the result 4.32 +/- 0.20 GeV is compatible with the experimental data, which supports Y (4360)'s P-wave [cq][(c) over bar(q) over bar] structure.
