Flavor Oscillations, the case of leptons
In the neutrino sector neutral particle oscillation occurs which gives rise to neutrino oscillation. From my currrent understanding , the observation of the neutrino oscillation occurred because the ...

Comparison between two flavor neutrino oscillation and a system of up-spin and down-spin states of an electron?
In the system of up-spin and down-spin states of an electron, we can write a general state of electron at time $t$ as
$$\left|\psi(t)\right>=a\left|\uparrow\right>+b\left|\downarrow\right>,$$...

Could neutrino oscillations be due to exchange of gamma rays?
I was wondering since the relativistic mass-energy of a gamma ray photon is 1.24 MeV/c^2 and the mass of an electron neutrino is < 2.2 eV/c^2 whether the oscillations between the two could, in the ...

Do electrons oscillate into muons just like electron-neutrinos into muon-neutrinos?
And if not, why? What is the difference to neutrinos oscillations?

Neutrino mass and the Majorana equation
I can't seem find this on the Internet. What does the Majorana equation predict neutrino masses to be (if they were their own antiparticle), and how?
(I have little understanding of spinors, btw...)

Derivation of neutrino oscillation phase factor
As we know, the neutrino $\nu_{\alpha}$ with flavor $\alpha=e,\mu,\tau$ is a linear combination of mass eigenstates:
$$
|\nu_{\alpha}\rangle=\sum_iU_{\alpha i}|\nu_i\rangle,\quad i=1,2,3
$$
where the ...
