Measurements of Branching Fraction, Polarization, and Direct CP-Violating Asymmetry in B{sup +} --> K*{sup 0} {rho}{sup +} decays
The purpose of this analysis is the simultaneous measurement of the branching fraction, the longitudinal-polarization component, and the direct-CP-violating charge asymmetry for the B --> vector-vector decay mode B{sup +} --> K*{sup 0}{rho}{sup +}, which has previously not been seen experimentally. The measurement of the polarization of the penguin decay is of special interest. There is no tree contribution to the decay amplitude and only a very small annihilation process. The polarization of the B{sup +} --> K*{sup 0}{rho}{sup +} decay mode can be compared to that already measured for the similar penguin decay B --> K*{phi}.
