  Boosted dark matter (BDM) is a well-motivated class of dark matter (DM)
candidates in which a small component of DM is relativistic at the present
time. We lay the foundation for BDM searches via hadronic interactions in large
liquid-argon time-projection chambers (LArTPCs), such as DUNE. We investigate
BDM-nucleus scattering in detail by developing new event generation techniques
with a parameterized detector simulation. We study the discovery potential in a
DUNE-like experiment using the low threshold and directionality of hadron
detection in LArTPCs and compare with other experiments.
