 Measurement of the branching fractions of the $B^0_s\to J/\psi\eta$, $B^0_s\to J/\psi\eta^{\prime}$ and $B^0\to J\psi\omega$ decays in the LHCb experiment / Savrina, Daria First evidence of the $B^0\to J/\psi\omega$ decay is found and the $B^0_s\to J/\psi\eta$ and $B^0_s\to J/\psi\eta^{\prime}$ decays are studied using a dataset corresponding to an integrated luminosity of 1.0 $\mathrm{fb}^{-1}$ collected by the LHCb experiment in proton-proton collisions at a center-of-mass energy of $\sqrt{s} = 7$ TeV.
