|Title:||New Models, Dark Matter Experiments, and Neutrino Searches at the High-Energy Intensity Frontier – Resonant SIDM, FORMOSA, LongQuest, and Forward Neutrino Campus|
|Date:||Wed, Dec 09, 2020, 10:00 - 11:00|
In this talk, I will give a general overview of experimental facilities with both high energies and high intensities, and how they can help explore dark matter models, complementary to astrophysical and cosmological searches. I will then talk about my new experimental proposals (FORMOSA, LongQuest, & Forward-DUNE) utilizing these facilities to study dark-sector models, including millicharged particles and portals to the dark sector, and neutrino physics.
I will then discuss the possibility of constructing a TeV "Forward Neutrino Campus" at the LHC forward physics region, using Forward Proto-DUNE and FORMOSA as examples. Forward Proto-DUNE can help fill in the gap between low-energy and high-energy neutrino cross-section measurements, and FORMOSA can study tau neutrino electric dipole moment.
Finally, I will discuss a new model, Resonant Self-Interacting Dark Meson, and tie it to the accelerator searches at the high energy-intensity frontier. I will also discuss how observations on the galactic scales can help distinguish different models.
If I have time, I will mention how to use precessions of exoplanets and trans-Neptunian objects (TNOs) to study ultralight axions.
