Measurement of the ratio of branching fractions B(B+c→J/ψK+)/B(B+c→J/ψπ+)

The ratio of branching fractions RK/π ≡ ℬ(Bc+ → J/ψK+)/ℬ(Bc+ → J/ψπ+) is measured with pp collision data collected by the LHCb experiment at centre-of-mass energies of 7 TeV and 8 TeV, corresponding to an integrated luminosity of 3 fb−1. It is found to be RK/π = 0.079 ± 0.007 ± 0.003, where the firs...
