Table 2.
The measured values of f(Q
0) for Q
0=25, 75 and 150 GeV for the different rapidity intervals used to veto jet activity are presented. The predictions from the NLO and multi-leg LO generators are also presented; the statistical uncertainty due to limited sample size is shown if this uncertainty is larger than 0.1 %. In each rapidity interval, the statistical correlations (
) between measurements at Q
0=i and Q
0=j are given
