Mesons Flip Between Matter and Antimatter

Posted by ryuzaki0 on from the make-up-your-mind dept.

steve writes "A team of over 700 physicists at Fermilab's Tevatron accelerator have observed the B-sub-s meson oscillating between matter and antimatter states at 3 trillion times a second. From the Fermilab press release: 'Immediately after the Big Bang some 13 billion years ago, equal amounts of matter and antimatter formed. Much of it quickly acted to annihilate the other, but for little-understood reasons, a bit more matter than antimatter survived, providing the universe with the planets, stars and galaxies visible today.' The Standard Model predicted the oscillation, and Fermilab has been working for 19 years to confirm it. The announcement is good press for Fermilab, which is pushing Congress to build a new 18-mile-long International Linear Collider."

    Did they just call the visible universe only a bit?

    Scary? I don't think it would really matter....

    I think these mesons have caused some problems on the Slashdot main page. When looking at the article, I saw this:

    Someone must have snuck in an antimatter posting or something.

    B-sub-s Meson doesn't quite roll off the tongue in the press release.

    Since these Mesons flip between matter and anti-matter regularly, I propose calling them...

    Freemesons.
