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

# metadata.dc.description.abstract[].value
The relative rates of B-meson decays into J/ψ and ψ(2S) mesons are measured for the three decay modes in pp collisions recorded with the LHCb detector. The ratios of branching fractions ( B) are measured to be where the third uncertainty is from the ratio of the ψ(2S) and J/ψ branching fractions to μ + μ −.
