Neutral meson vs. neutrino oscillations

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.

It is hard to find similarities apart from "there is mixing".

What do you mean with "mesons can interact in their mass eigenstates"?
How do you want to measure the mass precise enough to use it for mixing measurements?

Neutrino mixing is between neutrinos, or between antineutrinos, while neutral mesons are mixing with their own antiparticles.
You can also discuss CP violation and how it is relevant in the different cases.
 
Toponium is a hadron which is the bound state of a valance top quark and a valance antitop quark. Oversimplified presentations often state that top quarks don't form hadrons, because they decay to bottom quarks extremely rapidly after they are created, leaving no time to form a hadron. And, the vast majority of the time, this is true. But, the lifetime of a top quark is only an average lifetime. Sometimes it decays faster and sometimes it decays slower. In the highly improbable case that...
I'm following this paper by Kitaev on SL(2,R) representations and I'm having a problem in the normalization of the continuous eigenfunctions (eqs. (67)-(70)), which satisfy \langle f_s | f_{s'} \rangle = \int_{0}^{1} \frac{2}{(1-u)^2} f_s(u)^* f_{s'}(u) \, du. \tag{67} The singular contribution of the integral arises at the endpoint u=1 of the integral, and in the limit u \to 1, the function f_s(u) takes on the form f_s(u) \approx a_s (1-u)^{1/2 + i s} + a_s^* (1-u)^{1/2 - i s}. \tag{70}...
