DESCRIPTION:Until fairly recently\, the ATLAS experiment has been relative
 ly blind to the possibility that the particles we are trying to discover b
 eyond 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 signa
 tures of long-lived particles. The recently-submitted ATLAS DV+Jets search
  is one of such efforts\, searching for displaced vertex (DV) signatures c
 aused by when these long-lived BSM particles finally decay into charged st
 andard model tracks in the inner detector. This unique signature allows th
 ese analyses to be fairly general\, as well as sensitive to supersymmetry\
 , Higgs portal\, and other exotic model interpretations.
