The Strategy of Discrimination between Flavors for Detection of Cosmogenic Neutrinos

Understand

We propose a new method to identify flavors of ultra high energy cosmic neutrinos.

• Energy loss of leptons in matter provides important informations for the detection of neutrinos originated from high energy astrophysical sources.
• 50 years ago, Askaryan proposed to detect Cherenkov signals by radio wave from the negative charge excess of particle showers.
• The theory of Cherenkov pulses with Fraunhofer approximation was widely studied in the past two decades.
