Hello, I need to research online about the difference between neutral meson and neutrino oscillations. However I've found this difficult. I haven't found anywhere any comments on the differences between the two. The only thing which comes to mind is that the mesons can interact in their mass eigenstates as opposed to neutrinos so we can measure this mass. And that their weak eigenstates are not their flavour eigenstates as opposed to neutrinos where the weak are the flavour. Any insights please will be welcome.
