Measured fiducial cross sections and their corresponding uncertainties for each of the individual flavour categories, as well as for the combination of the four. The combined value is the result of a symultaneous fit to the four categories, therefore both the central value and its total uncertaintydiffer from the sum of the central values and the quadratic sum of the uncertainties respectively, because of correlations among sources of uncertainty in the categorized values.

Combined statistical and systematic uncertainties are shown for each case except for the observed data yields for which only statistical uncertainties are presented. All expected yields correspond to quantities estimated after the maximum likelihood fit.

Summary of the total postfit impact of each uncertainty source on the uncertainty in the signal strength measurement, for the four flavour categories and their combination. Theoretical uncertainties are only included in the signal acceptance during the extrapolation to the total phase space, so they are not included in the likelihood fit. The values are percentages and correspond to half the difference between the up and down variation of each systematic uncertainty component.

Efficiencies estimated as transfer factors from the fiducial region to the signal region using generator-level information, for an integrated luminosity L of 35.9 inverse femtobarn. Statistical, scale, and PDF uncertainties are later propagated to the final cross section measurement.
