| Résumé : | A measurement is presented of the tÌt production cross section ÏtÌt 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 tÌt signal to the reconstructed mass spectrum of tÌt candidates in the data, in which events are subjected to a kinematic fit assuming a tÌt â W+bW-Ìb â 6 jets hypothesis. The measurement yields ÏtÌt |
