Abstract
We present quantification of the potential to detect dark photons through Higgs portal decays to dark fermion pairs, as first analyzed in 2016 by ATLAS. The Higgs portal is one of two potential decay patterns under study: through further simulation we can compare it with a theorized supersymmetric (SUSY) portal and determine differences in lepton jets generated through the two portals. Using PYTHIA, analyses were performed to determine vertex displacement and lepton jet detection rates as a function of dark photon decay widths. Expected detection rates were then combined with decay simulations to determine dark photon signals from the production channel from dark fermion decay. The results of this study will help inform the direction of future dark matter searches.
