Towards detection of ultra high energy neutrinos at the South Pole: Askaryan Radio Array experiment latest results and future prospects”
Year: 2024
Type: conference-paper
Abstract: The Askaryan Radio Array (ARA) is an in-ice ultrahigh energy (UHE, >10 PeV) neutrino experiment at the South Pole that aims to detect radio emissions from neutrino-induced particle cascades. ARA has five independent stations which together have collected nearly 30 station-years of livetime of data. Each of these stations searches for UHE neutrinos by burying in-ice clusters of antennas ∼200 meters deep in a roughly cubical lattice with side length ~20m. Additionally, the fifth ARA station (A5) has a beamforming trigger, referred to as the Phased Array, consisting of a trigger array of 7 tightly packed vertically-polarized antennas. In this proceeding, we review the physics results from ARA, report on the progress on the analysis of the full ARA data set, and discuss future prospects for ARA emphasizing the discovery potential and benefits for the radio community and future UHE energy detection experiments.
