SUMMARY

The discussion centers on the impact of complex phases on neutrino oscillations, highlighting that Fermi's results indicate a discrepancy between the mixing angles of neutrinos and anti-neutrinos. While the mixing angles themselves are real numbers, the overall oscillation can be influenced by an additional complex phase. This complex phase is crucial as it differentiates the behavior of neutrinos and anti-neutrinos due to the opposite signs associated with complex phases.

My understanding is that Fermi has results that show the mixing angle for neutrinos is not the same as the mixing angle for anti-neutrinos. Is there a theory that explains this?

The mixing angles/phases themselves are the same for neutrinos and anti-neutrinos as they are real numbers. The overall oscillation may be effected by an additional phase which is not real a real but instead a complex number. Only complex phases would show a difference between neutrino and anti-neutrino because the sign in front of complex phases is opposite for each.

I am slowly going through the maths behind neutrino oscillations in my blog series of posts

I will get to this complex phase soon.
