Initial-state and final-state radiation This uncertainty is evaluated in samples generated with different amounts of initial- and final-state radiation. The uncertainty ranges from 0.6 to 12.6%.

b-jet fragmentation The size of the uncertainty from the -jet modeling is evaluated in the pairs cross section analysis following the method described in Ref. [26]. The uncertainty arises from the difference between the fragmentation parametrizations preferred by SLD vs. LEP data. A 2.0% value is measured.

Jet reconstruction and identification The efficiency to reconstruct and identify jets is measured in both data and Monte Carlo [11, 12, 23, 24]. These efficiencies are slightly higher for Monte Carlo, and a small correction is applied to the simulated samples. The uncertainty on the Monte Carlo normalization due to this correction is 1%.
