Neutral particle oscillations / quantum number conservation

    Hello everyone,
    Why don't neutral particle oscillations have to obey conservation of (quark) flavor quantum numbers, with the example of neutral Kaon oscillations?

    Because weak interactions are not flavour diagonal. In general, you would expect mixing among particles whenever they have the same gauge quantum numbers unless there is a symmetry to forbid it.

    Why should they? There is no conservation law for quark flavors, the weak interaction can change them. The oscillations happen via the weak interaction.

    Edit: Too slow.
