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 long-lived neutral particles with masses in the 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–gluon fusion or in association with a W boson. …
