Description

Charmless B-meson decays into two vector mesons, B → VV, serve as a powerful probe for the dynamics of weak and strong interactions through their angular distributions. This report will introduce recent LHCb results on B → VV decays, including:

  1. First observation of CP violation and measurement of polarization in B+ → ρ(770)0 K*(892)+ decays
  2. Measurement of the branching fractions and longitudinal polarisations of B(s)0 → K(892)0 K\bar(892)0
    decays
  3. Measurement of CP violation in Bs0 → ϕϕ and search for B0 → ϕϕ
