I mean, the electron neutrino can transform in a muon neutrino after a while. And that surprised the physics community because the electron cant transform to a muon. But 1) cant the electron transform into a W and a W into a muon? 2) So, Why we say that the neutrino oscillate and the electron doesn´t? 3) Why we make all that mess of mixing angle? cant we say that the electron neutrino transforms into a W and then it transform into a muon neutrino? Sorry for my ignorance and thanks in advance for sharing your knowledge!
