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…

Measurement of relative branching fractions of B decays to $ψ (2 S)$ and $J / ψ$ mesons

LHCb Collaboration

The relative rates of B-meson decays into $J / ψ$ and $ψ (2 S)$ mesons are measured for the three decay modes in pp collisions recorded with the LHCb detector. The ratios of branching…

First observation of the decay Bc+ to J/psi pi+pi-pi+

LHCb collaboration, R. Aaij, C. Abellan Beteta +592

The decay Bc+ --> J/psi pi+pi-pi+ is observed for the first time, using 0.8 fb-1 of pp collisions at sqrt{s}=7 TeV collected by the LHCb experiment. The ratio of branching fraction…
