The search uses 36.1 fb$^{-1}$ of data collected in 2015 and 2016 by the ATLAS experiment at the Large Hadron Collider. Decays of the excited electron via a contact interaction into an electron and a pair of quarks ($eq\\bar{q}$) are targeted in final states with two electrons and two hadronic jets, and decays via a gauge interaction into a neutrino and a $W$ boson ($\\nu W$) are probed in final states with an electron, missing transverse momentum, and a large-radius jet consistent with a hadronically decaying $W$ boson. No significant excess is observed over the expected backgrounds. Upper limits are calculated for the $pp \\to ee^* \\to eeq\\bar{q}$ and $pp \\to ee^* \\to e\\nu W$ production cross sections as a function of the excited electron mass $m_{e^*}$ at 95% confidence level. The limits are translated into lower bounds on the compositeness scale parameter $\\Lambda$ of the model as a function of $m_{e^*}$. For $m_{e^*} < 0.5$ TeV, the lower bound for $\\Lambda$ is 11 TeV. In the special case of $m_{e^*} = \\Lambda$, the values of $m_{e^*} < 4.8$ TeV are excluded. The presented limits on $\\Lambda$ are more stringent than those obtained in previous searches.","hasPart":[{"@id":"https://doi.org/10.17182/hepdata.90452.v1/t1","@type":"Dataset","description":"The distribution of $m_{lljj}$ used to discriminate the signal from background processes in the $eejj$ channel.
