Recent studies of $B$-meson decays at the LHCb experiment have provided new insights into modes with vector–vector final states, including $B^+ \to \rho(770)^0 K^*(892)^+$, $B_s^0 \to J/\psi \overline{K}^*(892)^0$, and $B^0 \to \phi\phi$, as well as modes with charmless final states like $B_{(s)}^0 \to K^0 p \overline{p}$ and $B^+ \to \overline{\Lambda} p \overline{p} p$.
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.
