AbstractA measurement of the λ0b lifetime using the decay λ0b→ J/ψΛ in protonproton collisions at √s=7 TeV is presented. The data set, corresponding to an integrated luminosity of about 5 fb−1, was recorded with the CMS experiment at the Large Hadron Collider using triggers that selected dimuon events in the J/ψ mass region. The λ0b lifetime is measured to be 1.503 ± 0.052 (stat.) ± 0.031 (syst.) ps.
