This book was released on 2004 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: 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].
