Figure 2: Comparison of tagged jet properties for signal events (m
H = 130
GeV) and the three major backgrounds. The upper left plot shows the p
T of the leading tagged jet, the upper right plot shows the p
T of the jet with the second highest p
T. The lower left plot shows the product of the directions of the two tagged jets in pseudo-rapidity (η
j1 η
j2 ), and the lower right plot shows the difference in η between the two tagged jets (Δη). The enhancement at Δη of 0.5 in the VBF signal results from a single high p
T jet being reconstructed as two jets. The filter cut described in Section 2.1 has been applied to the W+jet and Z+jet Monte-Carlo data, but no trigger cuts have been applied. The distributions are normalized to unity. The vertical dotted lines show the cut values used in the analysis.
