[tex]K_l = \frac{d\bar{s} + s\bar{d}}{\sqrt{2}}[/tex]

[tex]K_s = \frac{d\bar{s} - s\bar{d}}{\sqrt{2}}[/tex]

This happens because [tex]K_0[/tex] is oscillating into its own antiparticle.

My question is, why the same is not applicable to the neutrinos? They do oscillate. So instead of ‘pure’ e, mu, tau neutrinos we do not observe superposition?
