Fig. 8.

The dilepton rapidity distributions for $Z/{\mathit{\gamma }}^{\ast }\to e^{+}{e}^{-}$ candidates with two central electrons in the mass regions $46<m_{ee}<66\text{GeV}$ (left), $66<m_{ee}<116\text{GeV}$ (middle) and $116<m_{ee}<150\text{GeV}$ (right). The simulated samples are normalized to the data luminosity. The multijet background shape is taken from a data control sample and normalized to the estimated yield of multijet events. The sum of all expected background and signal contributions is shown as a solid line with a hashed band detailing the statistical uncertainty and labelled “total (stat)”. The legend lists only background sources with a visible contribution
