| The distributions of (a) \pt and (b) $\abs{\eta}$ for the leading jet, (c) \pt and (d) $\abs{\eta}$ for the sub-leading jet, (e) $H_\mathrm{T}$, and (f) b jet multiplicity after the jets selection and before the \cPqb\ jet requirement. The expected distributions for \ttbar signal and individual backgrounds are shown after corrections based on control regions in data are applied; in each plot the last bin contains the overflow events. The ratios of data to the sum of the expected yields are given at the bottom of each panel. The error bars indicate the statistical uncertainties. |
