Abstract

The cross section for tt‾ production in the all-jets final state is measured in pp collisions at a centre-of-mass energy of 8 TeV at the LHC with the CMS detector, in data corresponding to an integrated luminosity of 18.4 fb⁻¹. The inclusive cross section is found to be 275.6 ± 6.1 (stat) ±37.8 (syst) ±7.2 (lumi) pb. The normalized differential crosssections are measured as a function of the top quark transverse momenta, p_T, and compared to predictions from quantum chromodynamics. The results are reported at detector, parton, and particle levels. In all cases, the measured top quark p_T spectra are significantly softer than theoretical predictions.
