### Observations of BS 0→ψ(2S)η and B(S) 0→ψ(2S)π+π- decays

Abstract:
First observations of the BS 0→ψ(2S)η, B0→ψ(2S)π+π- and BS 0→ψ(2S)π+π- decays are made using a dataset corresponding to an integrated luminosity of 1.0 fb-1 collected by the LHCb experiment in proton-proton collisions at a centre-of-mass energy of √s=7 TeV. 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. © 2013 CERN.
