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/psi mass region. The Lambda(0)(b) lifetime is measured to be 1.503 +/- 0.052 (stat.) +/- 0.031 (syst.) psengrestrictedAccessMeasurement of the Lambda(0)(b) lifetime in pp collisions at root s=7 TeVarticle700032320290007610.1007/JHEP07(2013)163Hadron-hadron scattering2-s2.0-84881656539
