dc.description.abstractA measurement is presented of the tt¯ production cross section (σtt¯) in proton-proton collisions at a centre-of-mass energy of 7 TeV, in the all-jet final state that contains at least six jets, two of which are tagged as originating from b quarks. The data correspond to an integrated luminosity of 3.54 fb−1, collected with the CMS detector at the LHC. The cross section is determined through an unbinned maximum likelihood fit of background and tt¯ signal to the reconstructed mass spectrum of tt¯ candidates in the data, in which events are subjected to a kinematic fit assuming a tt¯→W+bW−b¯ → 6 jets hypothesis. The measurement yields σtt¯ = 139 ± 10 (stat.) ± 26 (syst.) ± 3 (lum.) pb, a result consistent with those obtained in other tt¯ decay channels, as well as with predictions of the standard model.en_US
