¹ AABOUD 2018BK based on 79.8 fb${}^{-1}$ of data. The observed significance is 5.8$\sigma $ relative to the background-only hypothesis. The measurement is consistent with the NLO SM prediction of $507$ ${}^{+35}_{-50}$ fb. See Table 3 and Fig. 5 for measurements of individual modes. Combined with the measurements at 7 and 8 TeV, the observed significance is 6.3$\sigma $.
