Recent studies of B-meson decays at the LHCb experiment have provided new insights into modes with vector–vector final states, including B^+ (770) ⁰ K^* (892) ^+, Bₛ⁰ J/ K^* (892) ⁰, and B⁰, as well as modes with charmless final states like B (ₒ) ⁰ K⁰ p p and B^+ p p p. Precise measurements of their branching fractions, CP asymmetries, and polarisation observables serve as tests of the Standard Model, where deviations could signal the presence of new physics.
