Measurement of the branching ratio Γ(Λ b 0 →ψ(2S)Λ 0 )/Γ(Λ b 0 →J/ψΛ 0 ) with the ATLAS detector
An observation of the Λ b 0 →ψ(2S)Λ 0 decay and a comparison of its branching fraction with that of the Λ b 0 →J/ψΛ 0 decay has been made with the ATLAS detector in proton–proton collisions at s=8 TeV at the LHC using an integrated luminosity of 20.6 fb −1 . The J/ψ and ψ(2S) mesons are reconstructe...
