| dc.description | We investigate whether the anomalous tensor operators with the Lorentz structure σ<sub>μν</sub>(1 + γ<sub>5</sub>) ⊗ σ<sup>μν</sup>(1 + γ<sub>5</sub>), which could provide a simple resolution to the polarization anomaly observed in B→φK* decays, could also provide a coherent resolution to the large B(B ηK*) and survive bounds from B ηK decays. Parameter spaces satisfying all these experimental data are obtained, and found to be dominated by the color-octet tensor operator contribution. Constraints for the equivalent solution with (1 + γ<sub>5</sub>) ⊗ (1 + γ<sub>5</sub>) operators are also derived and found to be dominated by the color-singlet one. With the constrained parameter spaces, we finally give predictions for B<sub>s</sub> φφ decay, which could be tested at the Fermilab Tevatron and the LHC-b experiments. |
