Abstract
- 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 fractions ([Formula: see text]) are measured to be [Formula: see text] where the third uncertainty is from the ratio of the ψ (2 S ) and J / ψ branching fractions to μ <superscript>+</superscript> μ <superscript>-</superscript> .
