AB - A new technique is developed to identify dielectrons (e<sup>+</sup>e<sup>−</sup>) with Lorentz boost γ<inf>L</inf>?> 20 that produce one single merged cluster in the electromagnetic calorimeter of the CMS detector. The identification uses two multivariate models: one for the case where both electron tracks are reconstructed, and another where only one of the tracks is reconstructed. The efficiency is determined using proton-proton collision data collected at a center-of-mass energy of 13 TeV. Boosted J=ψ mesons decaying into e<sup>+</sup>e<sup>−</sup> pairs are used to estimate the efficiency of the model with two tracks, yielding an overall efficiency of 80%. The Z → μþμ−γ events, where the photon converts into a collimated dielectron, are used for the model with a single track, yielding an efficiency of about 60%. A dedicated energy correction for dielectron candidates is also developed using B<sup>±</sup> → J=ψK<sup>±</sup> → e<sup>+</sup>e<sup>−</sup>K<sup>±</sup> data.
