title: "Auxiliary figure 4f" of "Search for light long-lived neutral particles from Higgs boson decays via vector-boson-fusion production from $pp$ collisions at $\sqrt{s}=13$ TeV with the ATLAS detector"

description: Observed (solid line) and expected (dashed line) 95% CL upper limits on B(H→ 2γ<sub>d</sub>+X) for FRVZ processes with a 125 GeV Higgs boson as a function of dark photon mean proper decay length for the ggF, WH and VBF analyses. The full combination is shown as solid or dashed black lines for a dark photon mass of 6 GeV.
description: A search is reported for long-lived dark photons with masses between 0.1 and 15 GeV, from exotic decays of Higgs bosons produced via vector-boson-fusion. Events that contain displaced collimated Standard Model fermions reconstructed in the calorimeter or muon spectrometer are probed to search for long-lived dark photon candidates that then decay into collimated jets of leptons or light hadrons. This search uses the full LHC Run 2 (2015-2018) data sample collected in proton-proton collisions at $\sqrt{s}$=13 TeV, corresponding to an integrated luminosity of 139 fb$^{-1}$. Dominant backgrounds from Standard Model processes and non-collision sources are estimated by using data-driven techniques. The observed event yields in the signal regions are consistent with the expected background. Upper limits on the Higgs boson to dark photon branching fraction are reported as a function of the mean dark photon proper decay length, or as a function of the dark-photon mass and kinetic mixing parameter that quantifies the coupling between the Standard Model and potential dark sector. These limits are also combined with previous ATLAS results obtained in the gluon-gluon fusion and WH production modes. A branching fraction above 10% is excluded at 95% CL for a Higgs boson decaying into two dark photons for dark-photon mean proper decay lengths between 173 and 1296 mm and mass of 10 GeV.
