6 Normalised differential cross-sections unfolded from data, compared with selected MC models, with respect to mT( ννb) and m( b). Data points are placed at the horizontal centre of each bin. See Sect. 1 for a description of the observables plotted scale, αS, and PDF uncertainties ...
Contributions from the X or B quark in the (X5/3, T ) or (T, B) doublet models are neglected, leading to conservative limits. – 15 – 1 ATLAS s = 13 TeV, 36.1 fb-1 Limit at 95% CL 10−1 Observed limit Expected limit Expected limit ± 1 σ Expected limit ± 2 σ T T ...
