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.…

Searching for millicharged particles with 1 kg of Skipper-CCDs using the NuMI beam at Fermilab

Santiago Perez, Dario Rodrigues, Juan Estrada +57

Oscura is a planned light-dark matter search experiment using Skipper-CCDs with a total active mass of 10 kg. As part of the detector development, the collaboration plans to build…
