Matter-Antimatter Bias Seen In Fermilab Collisions

ubermiester writes "The New York Times is reporting that scientists at Fermilab have found evidence of a very small (about 1%) average difference between the amount of matter/antimatter produced in a series of particle collisions. Quoting: '[T]he team, known as the DZero collaboration, found that the fireballs produced pairs of ... muons ... 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 finding invites theorists to explain why there is so much more matter than antimatter in the universe, when the Standard Model suggests that there should be equal amounts of each." Here is the paper as submitted to Physical Review (PDF). The DZero team is looking forward to getting detailed data from the LHC once it ramps up operationally.

    What makes the difference in this bias of what matters?

    What other thing can beat out antimatter evil?

    Just ask a Beatle. and a warm gun.

    Dark matter, Dark energy, Anti-matter... What next? Anti-energy.

    Anyone have any examples of Anti-energy?

    Mmm hmm. And your manner of speech is utterly jackass.

    I've been there, and over all it was a poor experience. A lot of ignorance.

    wow. that's a lot of crap.

    Nice made up number to protect you 'faith'. Falwell would be proud.
