Query: An exploratory study of the impact of CMS double-differential top
  distributions on the gluon parton distribution function   LHC $t\bar{t}$ data have the potential to provide constraints on the gluon
distribution, especially at high $x$, with both ATLAS and CMS performing
differential measurements. Recently, CMS has measured double-differential
$t\bar{t}$ distributions at 8 TeV. In this paper we examine the impact of this
data set on the gluon distribution. To that end we develop novel,
double-differential NNLO predictions for that data. No significant impact is
found when the CMS data is added to the CT14HERA2 global PDF fit, due to the
larger impact of the inclusive jet data from both the Tevatron and the LHC. If
the jet data are removed from the fit, then an impact is observed. If the CMS
data is scaled by a larger weight, representing the greater statistical power
of the jet data, a roughly equal impact on the gluon distribution is observed
for the $t\bar{t}$ as for the inclusive jet data. For data samples with higher
integrated luminosity at 13 TeV, a more significant impact of the
double-differential $t\bar{t}$ data may be observed.
