Welcome to the website of the ARIANNA Collaboration.

Set in the Antarctic, the now decommissioned ARIANNA pilot experiment pushed the boundaries of UHE neutrino physics to new limits, attempting to understand some of the most awe-inspiring objects in our universe.

With a unique combination of archival data and the continued development of innovative analysis tools, the ARIANNA collaboration continues to publish cutting edge papers that may help to inform the design of future radio-based neutrino detectors. A quick highlight of recent work

  1. A set of new cuts were developed to exploit the unique design of the ARIANNA station, which include both upward facing directional antennas, downward facing directional antennas, and one dipole buried at a depth of 10 m. These cuts, which include artificial intelligence techniques, were tested and verified using archival ARIANNA data.
  2. A new study of rare backgrounds based on radio signals generated by cosmic rays (which interact in the atmosphere) which then enter the ice and then reflected by imperfections in the ice back up to the neutrino detectors near the surface. These studies can be checked with archival ARIANNA data.
  3. We are actively developing a new trigger for radio neutrino detectors that offer the potential to improve sensitivity to neutrinos while reducing costs. The core idea uses artificial intelligence to exploit the unique signal features from the powerful ARIANNA antennas. Once again, we plan to use archival ARIANNA data to verify the capabilities of the AI-focused trigger system.

This website is a hub for the collaboration as well as the interested public who are interested to learn more.
