Distributions of the expected and observed number of events for the reconstructed event categories in the mass region $105<m_{4\ell }<140\text{GeV}$. Points with error bars represent the data and stacked histograms represent the expected numbers of the signal and background events. The yields of the different H boson production mechanisms with $m_{\mathrm{H}}=125\text{GeV}$, denoted as $\mathrm{H}(125)$, and those of the $\mathrm{Z}\mathrm{Z}$ and rare electroweak backgrounds are normalized to the SM expectations, while the $\mathrm{Z}$+X background yield is normalized to the estimate from the data
