A measurement of the
$ \Lambda_{\mathrm{b}}^0 $
lifetime using the decay
$ {{{\Lambda_{\mathrm{b}}^0\to J}} \left/ {{\psi \varLambda }} \right.} $
in protonproton collisions at
$ \sqrt{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
$ \Lambda_{\mathrm{b}}^0 $
lifetime is measured to be 1.503 ± 0.052 (stat.) ± 0.031 (syst.) ps.
