Description

Detailed studies have been carried out on the impact of top pair production data from the LHC on the gluon PDF, in the context of the CTEQ-TEA global PDF fit. The data includes single differential distributions from ATLAS at and double differential distributions from CMS, both at 8 TeV. The relative impact of different physical observables related to top quark production was considered. All analyses have been carried out at NNLO using fastNNLO tables constructed by the authors of the NNLO top production cross section.
