Rates, Polarizations, and Asymmetries in Charmless Vector-Vector B Meson Decays

With a sample of approximately 89 million BB pairs collected with the BABAR detector, we perform a search for B meson decays into pairs of charmless vector mesons (φ, ρ, and K*). We measure the branching fractions, determine the degree of longitudinal polarization, and search for CP violation asymmetries in the processes B+ → φK*+, B0 → φK*0, B+ → ρ0K*+, and B+ → ρ0ρ+. We also set an upper limit on the branching fraction for the decay B0 → ρ0ρ0
