| description | Differential cross sections of ttbar production have been measured by the ATLAS experiment at the LHC. Monte Carlo calculations provide an overall good modeling of all measured distributions, except for the transverse momentum of the top quark, for which all the generators at the next-to-leading order produce harder spectra. These measurements have been also included in the PDF fits, contributing to a sensible reduction of the gluon PDF uncertainty at large x. |
