Table 3.

Number of expected background and signal events and number of observed candidates after full analysis selection, for each event category, in the mass range $105<m_{4\ell }<140\text{GeV}$ and for an integrated luminosity of $137{\text{fb}}^{-1}$. The yields are given for the different production modes. The uncertainties listed are statistical only. Signal is estimated from MC simulation at $m_{\mathrm{H}}=125\text{GeV}$, $\mathrm{Z}\mathrm{Z}$ and rare electroweak backgrounds are also estimated from MC simulation, and $\mathrm{Z}$+X is estimated from data
