Query: Searches for Decays of New Particles in the DUNE Multi-Purpose Near
  Detector   One proposed component of the upcoming Deep Underground Neutrino Experiment
(DUNE) near detector complex is a multi-purpose, magnetized, gaseous argon time
projection chamber: the Multi-Purpose Detector (MPD). We explore the
new-physics potential of the MPD, focusing on scenarios in which the MPD is
significantly more sensitive to new physics than a liquid argon detector,
specifically searches for semi-long-lived particles that are produced in/near
the beam target and decay in the MPD. The specific physics possibilities
studied are searches for dark vector bosons mixing kinetically with the
Standard Model hypercharge group, leptophilic vector bosons, dark scalars
mixing with the Standard Model Higgs boson, and heavy neutral leptons that mix
with the Standard Model neutrinos. We demonstrate that the MPD can extend
existing bounds in most of these scenarios. We illustrate how the ability of
the MPD to measure the momentum and charge of the final state particles leads
to these bounds.
