Matter-antimatter bias seen in Fermilab collisions

ubermiester (883599) writes "The NYTimes is reporting that scientists Fermilab have found evidence of a very small (about 1%) average difference between the amount of matter/anti-matter produced in a series of particle collisions. FTA: "[T]he team, known as the DZero collaboration, found that the fireballs produced pairs of the particles known as muons, which are sort of fat electrons, slightly more often than they produced pairs of anti-muons. So the miniature universe inside the accelerator went from being neutral to being about 1 percent more matter than antimatter." This offers a possible explanation for why there is so much more matter than anti-matter in the universe in spite of "Big Bang" theory suggesting that there should be equal amounts of both. (Here's a PDF version of the paper.)"
