Table 5.

The relative fractions $n_j^{(\text{b-jet})}$ of events for the resolved selection for which out of the four leading small-R jets of the event, j jets contain at least one b-quark with $p_T^b\ge 15$ GeV. This information is provided for the di-Higgs signal events and for the three QCD background samples. The last column indicates the overall selection efficiency as defined in Eq. (10)
