Description
I will introduce a new dark matter model, resonant self-interacting dark meson (RSIDM), and talk about its implications on small-scale structure observations and the experimental signatures.
I will then give a general overview of experimental facilities with high energies and high intensities, focusing on proton fixed-target (at Fermilab) and hadron collider experiments (at the LHC). I will classify the searches as "decay" searches and "scattering" searches, and detail the new physics models of interest. These experiments can help close the gap between the low-mass/high-mass gap for the dark sector searches, and the low-energy/high-energy gap for the neutrino study.
I will present two new experimental proposals, LongQuest and FORMOSA. LongQuest is a multi-purpose proton fixed-target experiment, studying the decay particles, including dark photons and axion-like particles. FORMOSA is a specialized LHC forward experiment that is the world-most sensitive proposal to study millicharged particles, and also has the potential ability to study heavy neutrino and tau neutrino dipole moments.
Finally, I will discuss the possibility of constructing liquid Argon neutrino detectors at the LHC forward physics region to study high-energy neutrino cross-sections, named nu-FLArE. This talk is based on arXiv:2008.08608, arXiv:1908.07525, arXiv:2010.07941, arXiv:1812.03998, and ongoing works.
