Limits on the ultra-high energy electron neutrino flux from the RICE experiment

Upper limits are presented on the diffuse flux of ultra-high energy νe, based on analysis of data taken by the RICE experiment during August, 2000. The RICE receiver array at South Pole monitors cold ice for radio-wavelength Cherenkov radiation resulting from neutrino induced in-ice showers. For ene...

Description
Summary:Upper limits are presented on the diffuse flux of ultra-high energy νe, based on analysis of data taken by the RICE experiment during August, 2000. The RICE receiver array at South Pole monitors cold ice for radio-wavelength Cherenkov radiation resulting from neutrino induced in-ice showers. For energies above 1 EeV, RICE is an effective detector of over 15 km3 sr. Potential signal events are separated from backgrounds using vertex location, event reconstruction, and signal shape. These are the first terrestrial limits exploiting the physics of radio-Cherenkov emissions from charged current νe+N→e+N′ interactions. © 2003 Elsevier B.V. All rights reserved.
