Search for light long-lived neutral particles that decay to collimated pairs of leptons or light hadrons in $pp$ collisions at $\sqrt{s}=13$ TeV with the ATLAS detector

A search for light neutral long-lived particles with masses in the \textit{O}(MeV--GeV) range is presented. The analysis targets the production of long-lived dark photons in the decay of a Higgs boson produced via gluon fusion, or in association with a $W$ boson. Events that contain displaced collim...
