Shouldn't the particle and anti-particle in a meson annihilate?

  1. Oct 24, 2009 #1
    I've been wondering ever since I read about mesons, how they can exist. Shouldn't the particle anti-particle pair annihilate? Or is there something I'm missing from my idea of the meson?

    The can and they do. That's why mesons are unstable.
