Search for Dark Photons in Rare Z Boson Decays with the ATLAS Detector
Original language description
A search for events with a dark photon produced in association with a dark Higgs boson via rare decaysof the standard model Z boson is presented, using 139 fb-1 of ffiffiffi sp1/4 13 TeV proton-proton collision datarecorded by the ATLAS detector at the Large Hadron Collider. The dark boson decays into a pair of darkphotons, and at least two of the three dark photons must each decay into a pair of electrons or muons,resulting in at least two same-flavor opposite-charge lepton pairs in the final state. The data are found to beconsistent with the background prediction, and upper limits are set on the dark photon's coupling to thedark Higgs boson times the kinetic mixing between the standard model photon and the dark photon, αDε2,in the dark photon mass range of [5, 40] GeV except for the ϒ mass window [8.8, 11.1] GeV. This searchexplores new parameter space not previously excluded by other experiments.
