Millicharged Particles and Inelastic Dark Matter at the DUNE Near-Detector Complex

Not scheduled
10m

Speaker

Dr Yu-Dai Tsai (Fermilab)

Description

The DUNE Near-Detector (ND) complex, including LArTPC and HPgTPC detectors, provides a powerful multi-purpose facility to search for dark-sector particles, produced when 120 GeV proton beam (~10^21 POT/yr) hits the LBNF target. In this talk, I will discuss two types of searches: decay and scattering.
For the decay search, I will talk about a sub-GeV dark matter (DM) candidate, inelastic dark matter (iDM), that also has a long-lived state to be searched for in DUNE. DUNE can provide one of the strongest probes of iDM in the MeV-GeV regime. For the scattering search, I will present a study of the millicharged particle (MCP), a stable particle carrying fractional charges in the LArTPC detector. DUNE can provide leading sensitivity to MCPs and strongly interacting DM that cannot be seen in traditional direct-detection experiments. Finally, I briefly discuss scattering-plus-decay studies.
