Near as I can tell, you'd wind up with either wandering quarks (which I've read is impossible, due to the force gluons create increasing with distance), or some bizarre new particle composed of both matter and antimatter. Any of you physics folks willing to chime in here?

The kaon-antikaon pair is an interesting result, though, especially since kaons are as close to mixed matter-antimatter as you're going to find. Very strange little particles.
