Measurement of the Branching Fraction of B^{0} \rightarrow J/ψ π^{0} Decays

The ratio of branching fractions between B^{0} \rightarrow J/\psi \pi^{0} and B^{+} \rightarrow J/\psi K^{*+} decays is measured with proton-proton collision data collected by the LHCb experiment, corresponding to an integrated luminosity of 9 fb^{-1}. The measured value is $\frac{\mathcal{B}_{B^{0} \rightarrow J/\psi \pi^{0}}}{\mathcal{B}_{B^{+} \rightarrow J/\psi K^{*+}}} = (1.153 \pm 0.053... Show more
