Abstract:

The ANtarctic Impulse Transient Antenna (ANITA) is the first long-duration balloon experiment designed to search and measure the flux of Greisen- Zapsepin-Kuzmin (GZK) neutrinos. We present new limits on neutrinos fluxes of astronomical origin from data collected with the successful launch of a 2- antenna prototype instrument, called ANITA-lite, that circled the Antarctic continent for 18.4 days in January 2004. We performed a search for Ultra- High-Energy (UHE) neutrinos with energies above 3 x 1018 eV. No excess events above the background expectation were observed and a neutrino flux following E-2 spectrum for all neutrino flavors, is limited to Ev-2F < 1.6 × 10-6 GeV cm-2 s-1 sr-1 for 1018.5 eV < Ev < 1023.5 eV at 90% confidence level. The launch of ANITA is scheduled for December 2006. Looking beyond ANITA, we describe a new idea, called ARIANNA (Antarctic Ross Iceshelf ANtenna Neutrino Array), to increase the sensitivity for GZK neutrinos by one order of magnitude better than ANITA.

Constraints on cosmic neutrino fluxes from the Antarctic Impulsive Transient Antenna experiment.

Physical review letters 96:17 (2006) 171101

Abstract:

We report new limits on cosmic neutrino fluxes from the test flight of the Antarctic Impulsive Transient Antenna (ANITA) experiment, which completed an 18.4 day flight of a prototype long-duration balloon payload, called ANITA-lite, in early 2004. We search for impulsive events that could be associated with ultrahigh energy neutrino interactions in the ice and derive limits that constrain several models for ultrahigh energy neutrino fluxes and rule out the long-standing -burst model.

Current status of the ANITA experiment

Abstract:

• ANITA project has been progressing in amazing pace • instrument is well tested, understood, and calibrated with SLAC electron beam • ANITA is now ready to detect UHE neutrinos - collaborators heading for Antarctica - two calibration radio sources scheduled to be set up. • a nominal 15 days flight should cut into expected GZK flux • hope to have a longer flight (like 42 days CREAM '0405 flight) and a positive detection of GZK neutrinos.
