Observations of B s 0 → ψ ( 2 S ) η and B ( s ) 0 → ψ ( 2 S ) π + π − decays
First observations of the BS0→ψ(2S)η, B0→ψ(2S)π+π- and BS0→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 eac...
