Evidence for the decay $B^{0} \to J / ψ ω$ and measurement of the relative branching fractions of $B_{s}^{0}$ meson decays to $J / ψ η$ and $J / ψ η^{^{'}}$

LHCb Collaboration, R. Aaij, C. Abellan Beteta +620

First evidence of the $B^{0} \to J / ψ ω$ decay is found and the $B_{s}^{0} \to J / ψ η$ and $B_{s}^{0} \to J / ψ η^{'}$ decays are studied using a dataset corresponding to an integrated lumino…
