Measurement of the Branching Fraction of $B^0\to J/\psi {\pi }^0$ Decays

LHCb collaboration, R. Aaij, A. S. W. Abdelmotteleb +1071

The ratio of branching fractions between $B^0\to J/\psi {\pi }^0$ and $B^{+}\to J/\psi K^{\ast +}$ decays is measured with proton-proton collision data collected by the LHCb e…
