TABLE II.Mass resolutionbackground ratios (and number of events in the data ( �CB (see text) and FWHM (both in GeV), expected number of signal events (NS) for mH ¼ 120 GeV,ND) in each category for 4:9 fb�1, NS and ND are for the mass range 100–160 GeV
FIG. 1 (color online).Invariant mass distribution for the se-lected data sample, overlaid with the total background (see text).The bottom inset displays the residual of the data with respect tothe total background
FIG. 2.Reconstructed invariant mass distribution for a simu-lated signal of mH ¼ 120 GeV summed over all categories,superimposed with the fit to the signal model.
FIG. 4 (color online).Observed and expected 95% C.L. limitson the SM Higgs boson production normalized to the predictedcross section as a function of mH.
