Abstract
This work investigates the possibility that dark matter could be produced at the LHC, under the assumption that it is weakly coupled to the ordinary matter via a mixing parameter ε and that it constitutes a new sector of particles. Under the assumption of a neutral mediator, the dark photon, that decays promptly inside the ATLAS innermost detector volume, the lepton-jet signature, in which collimated leptons are reconstructed as a single object, is exploited. This work, based on the full Run-2 dataset, aims at extending the sensitivity of the previous Run-1 search to smaller branching ratios of the Higgs boson decaying to dark photons and to a wider dark photon mass range in the ε > 10−5 region.
