COSMOGENIC TAU NEUTRINO INDUCED RADIO EMISSION

Cosmogenic neutrinos1 are expected from ultrahigh energy cosmic rays undergoing the GZK process2,3 and anticipated to be observed by detection of the air showers from the decays of tau leptons. We use CORSIKA simulated shower structure to Calculate the coherent geosynchrotron radio emissions of the tau decay showers above 1017eV. We present the pattern and spectrum of the radio waves and discuss their detections by radio antennae. 1
