Why do Pions decay?

  1. Jun 20, 2011 #1
    I heard that (charged) Pions decay due to the weak force, but what does that have anything to do with it? Also, wouldn't the strong force hold them together?

    I actually came up with the idea of the Pion on my own before discovering that it had already been discovered.

    Also, could they be created by smashing a proton with an anti-neutron or an anti-neutron with a proton?

    Have you looked at anything else? Such as this article: http://en.wikipedia.org/wiki/Pion
    It and several of the links explain at least a couple of your questions.

    If you smash any two particles together with enough energy (enough to create π+π- pairs), you'll get pions. In high-energy particle physics experiments, pions are often a nuisance. They're the "small change" of particle physics.
