Unified Approach to Neutrino Oscillation and Decay Probabilities of Neutrino-Source Hadrons

Abstract

In the framework of quantum field theory, we examine what physical implications are included in the expectation values of the flavor neutrino charges at the time $x^0$ with respesct to the state $|\Psi (x^0)⟩$, which is taken so as to coincide with the neutrino source state such as a charged pion at the time $x_I^0$ ($<x^0$).
