Matter-Antimatter Bias Seen In Fermilab Collisions 304
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.

perhaps the "anti" in "antimatter" is dominate over the "identify matter" in "antimatter" and it sometimes acts as antiantimatter. so it isn't the universe giving a bias towards matter, it's antimatter being biased against itself.

Antimatter has declared the bias to be a clear-cut case of discrimination and has applied for status as a protected minority.

It doesn't matter. But it doesn't anti-matter, less.

Wasn't this the previously supposed hypothesis? That the big bang held a slight matter bias.
Slashdot has known this for more than a decade. After all, this isn't "news that anti-matters".

"I'm somewhat out of my depth here," said Bush, a longtime Fermilab follower who describes himself as "something of an armchair physicist." "But it seems to me that, when reducing the perturbative uncertainty in the determination of Vub from semileptonic Beta decays, one must calculate the rate of Beta events with a standard dilepton invariant mass at a subleading order in the hybrid expansion. The Fermilab folks' error, as I see it, was omitting that easily overlooked mathematical transformation and, therefore, acquiring incorrectly re-summed logarithmic corrections for the b-quark mass. Obviously, such a miscalculation will result in a precision of less than 25 percent in predicting the resulting path of the tau lepton once the value for any given decaying tau neutrino is determined."

Hawking radiation comes out of back holes. Because of quantum mechanics space is filled with virtual particles which come into existence and the annihilate themselves. Particles like an electron and an antielectron. Stuff like that. But if a black hole is nearby the electron could get swallowed, leaving the antielectron all alone in the world. The antielectron in this base becomes hawking radiation.

All right, okay. I should have read your post before I replied. How about this: particles come and go and nobody knows why. Sometimes they get lost which makes the other particles sad, so they wander off and get called "radiation".

Just tell Doppler to move out the way during the experiment, i'm sure he wouldn't mind.
God knows what he is doing up in space INSIDE the experiment chamber anyway. Sometimes i think that dude is getting a bit senile.

Probably will taste about the same as that anti-matter swill that you've been using.
Plus it'll be somewhat healthier as you wouldn't have total annihilation going on in your digestive tract so you wouldn't need to eat as many Tums afterwards.
