Differential crosssections are measured as a function of the transverse momentum and absolute rapidity of the top quark, and of the transverse momentum, absolute rapidity and invariant mass of the t (t) over bar system. The t (t) over bar events are selected by requiring one electron and onemuonof opposite electric charge, and at least two jets, one of which must be tagged as containing a b-hadron. The measured differential cross-sections are compared to predictions of next-to-leading order generators matched to parton showers and the measurements are found to be consistent with all models within the experimental uncertainties with the exception of the Powheg-Box + Herwig++ predictions, which differ significantly from the data in both the transverse momentum of the top quark and the mass of the t (t) over bar system.", optnote="WOS:000400987300001", optnote="exported from refbase (https://references.ific.uv.es/refbase/show.php?record=3152), last updated on Thu, 15 Jun 2017 12:09:07 +0000", issn="1434-6044", doi="10.1140/epjc/s10052-017-4821-x", opturl="http://arxiv.org/abs/1612.05220", opturl="https://doi.org/10.1140/epjc/s10052-017-4821-x", archivePrefix="arXiv", eprint="1612.05220", language="English" }
