The authors describe searches for B meson decays to the charmless vector-vector final states {omega}K*, {omega}p, {omega}{omega}, and {omega}{phi} with 233 x 10{sup 6} B{bar B} pairs produced in e{sup +}e{sup -} annihilation at {radical}s = 10.58 GeV. They also search for the vector-scalar B decay to {omega}f{sub 0}.

We present measurements of B meson decays to the final states [omega]K*, [omega][rho], and [omega]f0, where K* indicates a spin 0, 1, or 2 strange meson. The data sample corresponds to 465 x 106 B{bar B} pairs collected with the BABAR detector at the PEP-II ee− collider at SLAC. B meson decays involving vector-scalar, vector-vector, and vector-tensor final states are analyzed; the latter two shed new light on the polarization of these final states. We measure the branching fractions for nine of these decays; five are observed for the first time. For most decays we also measure the charge asymmetry and, where relevant, the longitudinal polarization f{sub L}.

Rare charmless hadronic B decays are particularly interesting because of their importance in understanding the CP violation, which is essential to explain the matter-antimatter asymmetry in our universe, and of their roles in testing the ''effective'' theory of B physics. The study has been done with the BABAR experiment, which is mainly designed for the study of CP violation in the decays of neutral B mesons, and secondarily for rare processes that become accessible with the high luminosity of the PEP-II B Factory. In a sample of 89 million produced B{bar B} pairs on the BABAR experiment, we observed the decays B{sup 0} {yields} {omega}K{sup 0} and B{sup +} {yields} {omega}{rho}{sup +} for the first time, made more precise measurements for B{sup +} {yields} {omega}h{sup +} and reported tighter upper limits for B {yields} {omega}K* and B{sup 0} {yields} {omega}{rho}{sup 0}.

This is written by Hluf Negash which studies the decays of B-meson in the framework of Bethe-Salpeter equation under covariant instantaneous ansatz. The analysis of this study gives important information about the internal structure of hadrons. The prediction of the properties of strongly interacting particles using the mesonic and baryonic sectors is of great importance since these hadrons can be easily produced in experiments and hence the theoretical predictions can be veri ed.
