Annotation

The reconstruction efficiency of photons and neutral pions is measured using the relative yields of reconstructed $B^{+}\to J/\psi K^{*+}(\to K^+\pi^0 )$ and $B^{+}\to J/\psi K^+$ decays. The efficiency is studied using the data set, corresponding to an integrated luminosity of $3 \mathrm{fb}^{-1}$, collected by the LHCb experiment in proton-proton collisions at the centre-of-mass energies of 7 and 8 TeV.
