Description
Summary:The Antarctic Impulsive Transient Antenna (ANITA) is an experiment which has completed two long-duration balloon flights above Antarctica. ANITA searches for impulsive radio-Cherenkov emission arising from the Askaryan charge excess which develops in ultra-high energy neutrino-induced particle cascades in the Antarctic ice. Analysis of data from the first ANITA flight, which took place in 2006-2007, resulted in zero neutrino candidate events remaining after all cuts had been performed. Limits on the ultra-high energy neutrino flux from this analysis are presented. The sensitivity of the second flight, 2008-2009, and possible future flights to both ultra-high energy neutrino and ultra-high energy cosmic ray air shower signals are discussed.
