| Abstract : | The exclusive FCNC beauty semileptonic decay B --> rho is studied using Ward identities in a general vector meson dominance framework, predicting vector meson couplings involved. The long distance contributions are discussed which results to obtain form factors and \V-ub\. A detailed comparison is given with other approaches., |
