abstract = {Several models of physics beyond the Standard
Model predict the existence of dark photons, light neutral
particles decaying into collimated leptons or light hadrons.
This paper presents a search for long-lived dark photons
produced from the decay of a Higgs boson or a heavy
scalar boson and decaying into displaced collimated StandardModel
fermions. The search uses data corresponding to
an integrated luminosity of 36.1 fb−1 collected in proton–
proton collisions at
√
s = 13 TeV recorded in 2015–2016
with the ATLAS detector at the Large Hadron Collider. The
observed number of events is consistent with the expected
background, and limits on the production cross section times
branching fraction as a function of the proper decay length of
the dark photon are reported.Across section times branching
fraction above 4 pb is excluded for a Higgs boson decaying
into two dark photons for dark-photon decay lengths between
1.5 mm and 307 mm.},
