Not much of anything interesting to say, so let me tell you why more matter than antimatter remains when you collide protons with antiprotons:
"The ratio of matter to antimatter in the experiment was revealed by observing a particular product of the collision, called B mesons. These particles are made up of one quark and one antiquark. B mesons, in turn, decay into other particles, including a type called muons. By studying the kinds of muons created in the collision, the researchers were able to calculate just how much more matter than antimatter resulted."I'll bet you didn't know that.
