Measurement of Charmless B to Vector-Vector decays at BaBar
The authors present results of B {yields} vector-vector (VV) and B {yields} vector-axial vector (VA) decays B{sup 0} {yields} {phi}X(X = {phi},{rho}{sup +} or {rho}{sup 0}), B{sup +} {yields} {phi}K{sup (*)+}, B{sup 0} {yields} K*K*, B{sup 0} {yields} {rho}{sup +}b{sub 1}{sup -} and B{sup +} {yields} K*{sup 0}{alpha}{sub 1}{sup +}. The largest dataset used for these results is based on 465 x 10{sup 6} {Upsilon}(4S) {yields} B{bar B} decays, collected with the BABAR detector at the PEP-II B meson factory located at the Stanford Linear Accelerator Center (SLAC). Using larger datasets, the BABAR experiment has provided more precise B {yields} VV measurements, further supporting the smaller than expected longitudinal polarization fraction of B {yields} {phi}K*. Additional B meson to vector-vector and vector-axial vector decays have also been studied with a view to shedding light on the polarization anomaly. Taking into account the available errors, we find no disagreement between theory and experiment for these additional decays.
