Search for the rare decays B0→J /ψ γ and Bs0→J /ψ γ
A search for the rare decay of a B0 or B0 s meson into the final state J/ψ γ is performed, using data collected by the LHCb experiment in pp collisions at √ s = 7 and 8 TeV, corresponding to an integrated luminosity of 3 fb−1 . The observed number of signal candidates is consistent with a background...
