Abstract
The decay Bc+→ψ(2S)π + with ψ(2S) →μ +μ - is observed with a significance of 5.2σ using pp collision data corresponding to an integrated luminosity of 1.0 fb -1 collected by the LHCb experiment. The branching fraction of Bc+→ψ(2S)π + decays relative to that of the Bc+→J/ψπ + mode is measured to be B(Bc+→ψ(2S) π +)B(Bc+→J/ψπ +)=0.250±0.068(stat) ±0.014(syst)±0.006(B). The last term is the uncertainty on the ratio B(ψ(2S)→μ +μ -)/B(J/ ψ→μ +μ -).
