With a sample of approximately 89×106 BB̅ 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.

Abstract

With a sample of approximately 89×106 BB̅ 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.
