How are Pions Produced in Nuclei?

[fujita969]

How are Pions produced inside a nucleus? I've heard it was through gluons exchange but found nothing about it.

Same way photons are produced by charged particles interacting and gluons are produced by quarks interacting. In this case, I think it's a manifestation of the Colour Force.

Could you explain it in more detail?
Also, browsing through wikipedia I found a Feynman diagram that seems to point when a pion is produced, however, it does not really tells how.

They come from a minimum uncertainty in the amount of energy measured.

http://en.wikipedia.org/wiki/Nuclear_force is probably even more helpful.
