About the pi0 meson:
I have a vague understanding of the idea of quantum super-position giving the linear combination of uubar and ddbar, even though it is very hard to picture - if possible I would like to avoid going off onto a tangent about this...
My question is: am I right in saying that the decay of pi0 is through EM?
Is it caused by annihilation of the 'quark/antiquark?' Is this a too simplistic way of looking at it?
Also: In general- why doesn't the strong force prevent annihilation of a quark-antiquark pair if it becomes repulsive at short distances? Or, is it naive of me to be thinking that the quark and antiquark actually need to "touch" to annihilate?
Any responses wold be welcome...
Thank you
