95\% exclusion confidence level on the signal strength multiplier for the SM Higgs search in the 5 Higgs decay channels. The solid lines indicate the observed exclusion and the dashed lines the expected.

BDT output for the 130 GeV $H \to WW \to 2\ell 2\nu$ selection. Top left: 0-jet opposite flavour, top right: 0-jet same flavour, bottom left: 1-jet opposite flavour and bottom right: 1-jet same flavour.

Left: 95\% exclusion on the relative signal strength to the SM in the $\gamma\gamma$ channel for the MVA based analysis. The dashed line indicates the expected limit for the cut based analysis. The yellow and green bands indicate the 1 and 2$\sigma$ expectations around the median expected result. Right: local p-value as function of the Higgs mass. The combined p-value is shown and the VBF tag and other inclusive classes individual contributions are also shown.

Fitted signal strength multiplier $\mu$ as function of the Higgs mass (left) and measured $\mu$ in the different channels at \MH = 125 GeV (right).

Mass spectrum of the ZZ$\to 4\ell$ candidates in the full mass range (left) and in the low mass range (right).

Left: VBF $\gamma\gamma$ candidate event display, Right: di-photon mass spectrum for all events passing the final selection. Data are shown together with the background MC prediction. The hatched area indicates the systematic error on the background normalization from the K-factors. The expected Higgs signal at 120 GeV is also shown superimposed and scaled by a factor 5.
