Comparison between data and the background estimate for the htlepmet distribution used in different vlle signal region categories:(a) 2ℓ(e)ℓℓHH, (b) 2ℓ(e)ℓℓHV, (c) 2ℓ(e)ℓℓVV, (d) 2ℓ(e)ℓνHW, (e) 2ℓ(e)ℓνWZ, (f) 3ℓ(e)ℓℓHH+HW, (g) 3ℓ(e)ℓνHV, (h) 3ℓ(e)ℓℓHV+VV, (i) 4ℓ(e)1OSSF, (j) 4ℓ(e)2OSSF.Distributions for one VLL_e^D signal point for a VLL mass of 600 GeV normalised to the total background yields are overlaid for comparison.The lower panels show the ratio of data to the background estimate (`B.'), separately for post-fit background (black points) and pre-fit background (dashed blue line).The size of the combined statistical and systematic uncertainty in the signal-plus-background prediction is indicated by the blue hatched band.
