Why is there more matter than antimatter?

It’s a social question and I’d like to start a thoughtful discussion. The question is very old, but many scientists are still puzzled. Are you too? A related question would be: Do you expect the Large Hadron Collider (LHC) to help scientists find an answer?

Here’s a quite recent article about the subject (it’s not a Wikipedia link, mind you…) but it’s not very specific in terms of a real explanation in my opinion. What exactly is the new statistical approach?

A classic explanation of course is: There is more matter than antimatter, because we humans are here. It’s called the anthropic principle. Some folks seem satisfied with this, but I’m not. Are you?
