Highly boosted dielectron identification in proton-proton collisions at $\sqrt{s} = 13~\mathrm{TeV}$ /CMS Collaboration
Searches for highly boosted new particles that decay to dielectron pairs can be challenging, as the relatively coarse granularity of many calorimeters and the size of their effective Moli$\mathrm{\grave{e}}$re radius can lead to their misidentification as single electrons. A new technique is developed to identify electron pairs in the range of Lorentz boost $\gamma > 20$ which produce one single merged cluster in the electromagnetic calorimeter of the CMS detector.
