Evidence for Higgs boson decay to a pair of muons
Left: the mμμ distribution for the weighted combination of VBF-SB and VBF-SR events. Each event is weighted proportionally to the S/(S+B) ratio, calculated as a function of the mass-decorrelated DNN output. The lower panel shows the residuals after subtracting the background prediction from the S+B fit. The best fit H→μ+μ− signal contribution is indicated by the blue line and histogram, while the grey band indicates the total background uncertainty from the background-only fit. Right: the mμμ distribution for the weighted combination of all event categories. The lower panel shows the residuals after background subtraction, with the best fit SM H→μ+μ− signal contribution for mH= 125.38 GeV indicated by the red line.
