Measurement of double-differential cross sections for top quark pair production in pp collisions at $$\sqrt{s} = 8$$ s = 8 $$\,\text {TeV}$$ TeV and impact on parton distribution functions
Normalized double-differential cross sections for top quark pair ([Formula: see text]) production are measured in pp collisions at a centre-of-mass energy of 8[Formula: see text] with the CMS experiment at the LHC. The analyzed data correspond to an integrated luminosity of 19.7[Formula: see text]. The measurement is performed in the …
