Hi all,(adsbygoogle = window.adsbygoogle || []).push({});

I'm can't wrap my head around this. I get how the strong interaction bonds quarks into baryons and I get the pion exchange model for the attraction between nucleons (well sort of, I still don't understand how exchanging massive particles can result in anattractiveforce, but OK).

What I don't understand is how the latter is a residual effect of the former. The color interaction leaves flavor untouched, but the pion exchanges flavors between (the quarks of) nucleons. So how exactly does the pion form?

There is a Feynman-Diagram in the Wikipedia article on nuclear force (http://en.wikipedia.org/wiki/Nuclear_force), but I don't understand that either. Not very good with Feynman diagrams.

Can anyone explain this to me in preferably plain English? I'm a physics student, so jargon is OK, but I have almost no background in QCD, so go easy on the maths, if possible.

Thanks in advance.
