Measurement of the $B^0\to \rho (770{)}^0\gamma$ branching fraction

LHCb collaboration, R. Aaij, A. S. W. Abdelmotteleb +1160

The ratio between the branching fractions of the $B^0\to \rho (770{)}^0\gamma$ and $B^0\to K^{\ast }(892{)}^0\gamma$ decays is measured with proton-proton collision data collected…
