Nuclear Recoils from Invisible Neutron-Pair Annihilation and the LZ event
Junseok Lee, Fuminobu Takahashi, Yu-Dai Tsai
Two bound neutrons can annihilate into a single invisible scalar carrying baryon number two, producing a monochromatic nuclear recoil. Pair removal connects the ground states…
Gravity Probe-DM: The Gravitational Laboratory for Dark Matter
Yu-Dai Tsai, Hayden R. Foote
Dark matter is inferred gravitationally across the Universe but has not been detected within the Solar System. The Sun inevitably focuses incident unbound dark matter into an irred…
Number Theory in Quantum Physics: Minicharged Particles and the Prouhet-Tarry-Escott Problem
Junseok Lee, Fuminobu Takahashi, Yu-Dai Tsai
In quantum gauge theories, anomaly cancellation severely restricts the allowed patterns of chiral charges. Here we show that, in a phenomenologically motivated framework for light…
Constraints on fifth forces and ultralight dark matter from OSIRIS-REx target asteroid Bennu
Yu-Dai Tsai, Davide Farnocchia, Marco Micheli +2
Using the OSIRIS-REx mission and ground-based tracking data for the asteroid Bennu, we derive new constraints on fifth forces and ultralight dark matter. The bounds we obtain are s…
Cosmic Millicharge Background and Reheating Probes
Xucheng Gan, Yu-Dai Tsai
We demonstrate that the searches for dark sector particles can provide probes of reheating scenarios, focusing on the cosmic millicharge background produced in the early universe.…
Neutrino Electromagnetic Properties and the Weak Mixing Angle at the LHC Forward Physics Facility
Roshan Mammen Abraham, Saeid Foroughi-Abari, Felix Kling +1
The LHC produces an intense beam of highly energetic neutrinos of all three flavors in the forward direction, and the Forward Physics Facility (FPF) has been proposed to house a su…
