Until fairly recently, the ATLAS experiment has been relatively blind to the possibility that the particles we are trying to discover beyond the standard model (BSM) do not decay promptly, due to assumptions built into the tracking and reconstruction algorithms. However, with the development of large-radius tracking we are now able to explore more signatures of long-lived particles. The recently-submitted ATLAS DV +Jets search is one of such efforts, searching for displaced vertex (DV) signatures caused by when these long-lived BSM particles finally decay into charged standard model tracks in the inner detector. This unique signature allows these analyses to be fairly general, as well as sensitive to supersymmetry, Higgs portal, and other exotic model interpretations.
