These correspond to absolute branching fractions of

Where, in the case of the modes, the ratio of fragmentation fractions is yet to be measured, so the product of the final branching fractions and this ratio are reported.

An example of the individual curves for each data category and the combined , including all systematics, for the branching fraction ratio, can be seen in Fig. 5.9.

5.6.1 Significances

Significances are calculated using the above-mentioned log-likelihood scans, where the significance in Gaussian standard deviations is given by , where is the difference in log-likelihood between the zero signal yield (null) model and the nominal fit model. The results of this can be seen in Table 5.9, which includes significances where only the statistical uncertainty on the total yield is taken into account, and where both the statistical and systematic uncertainties are included in the log-likelihood scan.
