A Low-threshold Neutrino Search with the Askaryan Radio Array: Results and Future Prospects

Neutrinos provide a unique window into the highest energy accelerators in the Universe. Due to only interacting weakly, they are capable of traveling directly from their sources to detectors built on Earth. They are ideal candidates for unraveling the mysteries of the ultra high energy cosmic ray flux and understanding particle physics at energies beyond the capabilities of detectors on Earth. Often, detectors are built in some of the most remote places on Earth to detect this very low flux at the highest energies.

In this talk, I will discuss new results from one neutrino detector, the Askaryan Radio Array (ARA), which targets neutrinos above 10 PeV. This result has shown improved efficiency at both the trigger level and the analysis level, and provides a baseline design for future neutrino detectors that are currently under construction around the world.
