First observations of the B0s→ψ(2S)η, B0→ψ(2S)π+π− and B0s→ψ(2S)π+π− decays are made using a dataset corresponding to an integrated luminosity of 1.0fb−1 collected by the LHCb experiment in proton–proton collisions at a centre-of-mass energy of s√=7TeV. The ratios of the branching fractions of each of the ψ(2S) modes with respect to the corresponding J/ψ decays are

where the third uncertainty corresponds to the uncertainties of the dilepton branching fractions of the J/ψ and ψ(2S) meson decays.
