Manifestations of the mixing
One manifestation of the mixing is flavor
oscillations e.g. ns, K0s
Another is the alteration of the decay strength.

A bit of history
Cabibbo proposed
However, it became clear that there was a neutral
component
Yet, the process KL0?mm- could not be
observed. Why not??
G.I.M. proposed
