Title: Search for light long-lived neutral particles produced in p p collisions at s = 13 TeV and decaying into collimated leptons or light hadrons with the ATLAS detector

Abstract

CERN-LHC. Search for long-lived dark photons produced from the decay of a Higgs boson or a heavy scalar boson and decaying into displaced collimated Standard Model fermions. The search uses data corresponding to an integrated luminosity of 36.1/fb collected in proton-proton collisions at 13 TeV center-of-mass energy and 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. Detection efficiency as a function of the proper decay lenght are also reported.
