| Özet |
| The cross sections for the production of t t¯ b b¯ and t t¯ jj events and their ratio σ t t¯ b b¯/σ t t¯ jj are measured using data corresponding to an integrated luminosity of 2.3 fb− 1 collected in pp collisions at s= 13 TeV with the CMS detector at the LHC. Events with two leptons (e or μ) and at least four reconstructed jets, including at least two identified as b quark jets, in the final state are selected. In the full phase space, the measured ratio is 0.022±0.003 (stat)±0.006 (syst), the cross section σ t t¯ b b¯ is 4.0±0.6 (stat)±1.3 (syst) pb and σ t t¯ jj is 184±6 (stat)±33 (syst) pb. The measurements are compared with the standard model expectations obtained from a powheg simulation at next-to-leading-order interfaced with pythia. |
