                      luminosity of 20.3 fb$^{-1}$ of proton--proton collisions at
                      a centre-of-mass energy of 8 TeV at the Large Hadron

                      cross-section times branching ratio for $t\bar{t}$ events
                      with at least one additional $b$-jet is measured to be 950

                      lepton-plus-jets channel and 50 $\pm$ 10 (stat.)

                      cross-section times branching ratio for events with at least
                      two additional $b$-jets is measured to be 19.3 $\pm$ 3.5

                      (syst.) fb using a looser selection that allows the
                      background normalisation to be extracted from data. The
                      latter method also measures a value of 1.30 $\pm$ 0.33
