Identification of highly boosted Ze+e decays with the ATLAS detectorDominik Duda, •Florian Kiwit, Sandra Kortner, and Hubert Kroha — Max-Planck-Institut für Physik

The identification of W, Z and Higgs bosons with large transverse momenta is crucial in many searches for new heavy resonances. Thus far, the development of algorithms for the tagging of boosted bosons focuses on the reconstruction and identification of hadronic boson decays, while no dedicated algorithm to identify boosted Ze+e decays exists. The performance of the standard electron reconstruction and identification algorithms degrades with decreasing angular separation between the e+e pairs and will eventually vanish once the angular separation between the e+e pairs is too small to construct individual clusters in the calorimeter. To improve the reconstruction and identification of such highly boosted Ze+e decays, a dedicated algorithm for Ze+e tagging is being developed using a deep neural network. This talk presents first results of this development.
