What happens in terms of neutrino oscillation if the distance is extremely high (much more than Sun-Earth distance) : is oscillation lost ? Why ?
Is there decoherence of oscillation ? What does this mean ?
Are astrophysics neutrinos (=very far distance) considered for neutrino oscillation ? If yes, how could it be if the oscillation is lost ?
Such figure makes believe that for extremely long distance, the oscillation would not be observable... (?)
