B -> rho K* decays and other rare vector-vector modes
G. Vasseur
The recent analyses of the following rare vector-vector decays of the B meson are presented:
rho K*, omega K*, omega rho, omega omega, and omega phi charmless final states. The latest results indicate that the fraction of longitudinal polarization is about 0.5 in penguin-dominated modes and close to 1 for tree-dominated modes.
