Flavor Transition Mechanisms of Propagating Astrophysical Neutrinos -A Model Independent Parametrization

Understand

One of the important goals for future neutrino telescopes is to identify the flavors of astrophysical neutrinos and therefore determine the flavor ratio.

• The flavor ratio of astrophysical neutrinos observed on the Earth depends on both the initial flavor ratio at the source and flavor transitions taking place during propagations of these neutrinos.
• We propose a model independent parametrization for describing the above flavor transitions.
• A few flavor transition models are employed to test our parametrization.
