Abstract

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 -. © 2012 CERN for the benefit of the LHCb collaboration.
