Abstract: | Using pp collisions corresponding to 3 fb−1 integrated luminosity, recorded by the LHCb experiment at centre-of-mass energies of 7 and 8 TeV, the ratio of branching fractions B(Λ0b→ψ(2S)Λ)/B(Λ0b→J/ψΛ)=0.513±0.023(stat)±0.016(syst)±0.011(B) is determined. The first uncertainty is statistical, the second is systematic and the third is due to the external branching fractions used. |
