That article didn't clear up a whole lot for me personally. Maybe some others are like me. I also read the actual CERN article, which this article copied almost entirely.
But after reading twice, what seems to be going on is that a particle has a slightly different mass from its antiparticle. (That is the most unbelievable sentence I have written so far this year! It's just... wow. I didn't think that was even theoretically possible.)
