A bstract Measurements of b -hadron lifetimes are reported using pp collision data, corresponding to an integrated luminosity of 1.0 fb −1 , collected by the LHCb detector at a centre-of-mass energy of 7 TeV. Using the exclusive decays B + → J/ ψ K + , B 0 → J/ ψ K ∗ (892) 0 , , and the average deca...
