ARIANNA  

Definition

  • ARIANNA: A New Frontier In UHE Particle Physics ARIANNA is a new neutrino telescope that can detect neutrinos with energies between 10^15 and 10^20 eV. The final telescope will consist of 960 detectors arranged in a grid of 30km x 30km. ARIANNA intends on detecting Cherenkov light at radio frequencies with specialized antenna and using these detections to learn more about some of the big questions in ultra-high energy particle physics including probing the GZK cutoff as well as possibly aiding the understanding of ultra-high energy neutrino sources. ARIANNA intends to answer, or at least help to answer, some pressing questions in high energy neutrino physics due to a variety of capabilities: - ARIANNA increases the sensitivity for the detection of GZK neutrinos by an order of magnitude over the state-of-the-art detectors currently under construction, such as ANITA. Simulations indicate that ARIANNA can observe ~ 40 events per 6 months of operation based on widely used predictions for the GZK neutrino flux by Engel, Steckel & Stanev. - ARIANNA can test alternative scenarios for GZK neutrino production. For example, models that assume that extragalactic cosmic rays are mixed elemental composition, or perhaps entirely iron nuclei, predict fluxes that may be as small as ~5% of the ESS predictions. - ARIANNA can survey the southern half the sky for point sources of high-energy neutrinos with unprecedented sensitivity. Preliminary reconstruction studies show that the neutrino direction be measured to a precision of 1 degree, and additional improvements in the reconstruction procedure are expected. These encouraging results show that good reconstruction can be achieved despite imprecise knowledge of the path of the signal. - ARIANNA can probe for physics beyond the standard model by measuring the neutrino cross-section at center of momentum energies of 100 TeV, a factor 10 larger than available at the LHC.
