摘要We investigate whether the anomalous tensor operators with the Lorentz structure (sigma(mu nu)(1 + gamma(5)) circle times sigma(mu nu) (1 + gamma(5)), which could provide a simple resolution to the polarization anomaly observed in B -> phi K* decays, could also provide a coherent resolution to the large B(B -> eta K*) and survive bounds from B -> eta K 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 + gamma(5)) circle times (1 + gamma(5)) 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-s ->phi phi decay, which could be tested at the Fermilab Tevatron and the LHC-b experiments.
