WebThe neutral pion has either up/anti-up or down/anti-down as its composition. Both of these combinations have identical quantum numbers and so the particle is found in superposition i.e. its "true" composition can only be said to be a mix of the two. A similar argument applies to the eta mesons. A good (imo) explanation is given here.
