Searching for possible evidences of new physics in B → V1V2

We explore the decays of B -> V1V2 (V-1,V-2 = (rho, omega, K*, phi) and B = (B-0, B+, B-s)) with transverse polarizations. We explicitly evaluate the eigenstates of T-odd scalar operators involving spins for the first time, which offer physical insight among the T violating observables. Based on the helicity suppression of tree operators for transverse polarizations in the standard model (SM), we deduce that Delta phi(p) = Delta phi(parallel to) - Delta phi(perpendicular to) = 0 with phi(perpendicular to parallel to), the weak phases of the transverse amplitudes. In contrast, the experiments show that Delta phi(p)(B-0 -> K-*0 omega) = -0.84 +/- 0.54, which could be a signal of new physics. There is also a discrepancy between our result in the SM and the experimental data for the transverse polarized branching ratio in B-0 -> K-*0 omega. In addition, by counting the helicity flips, we argue that sin(phi(parallel to) - phi(perpendicular to)) approximate to 0, which meets well with most of the experiments except for the ones with B-0 -> K-*0 omega, where phi(parallel to,perpendicular to) are the strong phases in the transverse amplitudes.

Automated summary

This study investigates the decays of B -> V1V2 (V-1,V-2 = (rho, omega, K*, phi)) under transverse polarizations and compares the results with experimental data. The findings suggest the possibility of new physics and discrepancies between the standard model predictions and experimental observations.
