I have a puzzle for you. How would you distinguish, in hackernews-level informal (but still reasonably accurate) prose, flavour-changing oscillation and wave frequency in the sense of E=hf? Doesn't the latter frequency imply an internal clock even for photons?
(For fun we could attribute an extremely tiny mass to photons and repeat the question, bearing in mind this necessarily ousts the photon from its (affinely-parametrizable but not proper-time-parametrizable) null worldline.)
- ajkjk 5y agoI don't know much about this off the top of my head, but roughly, the idea is that a neutrino we observe with a definite mass is a mixture of the three flavors, and a neutrino with a definite lepton flavor is a mixture of those with different masses. The different masses mean that as a neutrino of a certain flavor travels its different constituent states evolve at different speeds, so what it is measured at have different chances of being measured based on when the measurement takes place. Photons have no effect like this because they are not mixtures of different particles and have no concept of 'flavor'. Massive photons would be the same.
