A comparison of $\ttbar$ predictions of differential cross section with measurements performed by the ATLAS detector at LHC

A recent paper by the ATLAS Collaboration presented the normalized differential cross sections of $\ttbar$ in pp collisions at $\sqrt{s}=7$ TeV, with respect to $m_{\ttbar}$, $p_{T,\ttbar}$, $p_{T,t}$ and $y_{\ttbar}$. MCFM theoretical predictions at NLO QCD were produced with MSTW2008 PDF and used for estimating theoretical uncertainties for predictions. Theoretical uncertainties were assumed to originate from the uncertainties related to the PDF and the renormalization and factorization scales. Then the bins' correlation matrices were formed and used to calculate $\chi^2$ and $p$-values. For $m_{\ttbar}$ obtained values are $\chi^2=6.0$ and $p=0.20$, while for $p_{T,t}$ obtained values are $\chi^2=9.8$ and $p=0.14$. The results are compatible with the published data
