Particle tracked between real world, spooky realm
[color=#6600CC]The discovery that a bizarre particle travels between the real world of matter and the spooky realm of antimatter 3 trillion times a second may open the door to a new era of physics, Fermilab researchers announced Monday.
The incredibly rapid commuting rate of the B sub s meson particle had been predicted by the Standard Model, the successful but incomplete theory aimed at explaining how matter and energy interact to form the visible universe. After 20 years of trying, scientists have now confirmed the rate, providing strong evidence for the theory.
The monumentally precise technology developed to measure the meson's back and forth dashes also may open the way to discovering a new family of fundamental particles and possibly a set of new forces that could be harnessed for technological applications, physicists suggested.
The discovery comes at a time when the future of Fermilab, located near Batavia, Ill., is in doubt. Its huge 4-mile circular Tevatron particle accelerator may be forced to close by 2010 if Congress does not approve construction at Fermilab of a multibillion-dollar, 18-mile-long International Linear Collider.
Without the collider, the United States would lose its lead position in high-energy physics discoveries to Europe, where a new accelerator seven times more powerful than the Tevatron is to start up within two years at a site on the Swiss-French border.
The meson finding shows that Fermilab, which began operations in 1967, is still capable of making breakthrough discoveries. Scientists there discovered two of the most fundamental particles, the bottom quark in 1977 and in 1995 the top quark, one of the constituent particles of protons, which form the nuclei of atoms.
Raymond Orbach, undersecretary for science with the U.S. Department of Energy, called the breakthrough "a triumph for Fermilab."
"This remarkable tour de force details with exquisite precision how the antiworld is tied to our everyday realm," he wrote in a statement. "It is a beautiful example of how, using increasingly sophisticated analysis, one can extract discovery from data from which much less was expected."
For all that scientists have learned about the universe it is still a mysterious place. 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.
Particles that bridge the two worlds, such as the B sub s meson, normally don't exist on their own but can be created in the great collisions generated by particle accelerators, which attempt to duplicate conditions close to the Big Bang. Studying the particles helps scientists understand the evolution of the universe.
Fermilab's Tevatron collides protons against antiprotons moving near the speed of light, producing about 10 million collisions a second. The key to interpreting this enormous amount of data is the CDF detector, a three-story-high instrument that measures the tracks of the particles exploding from the collisions.
Such experiments are big and expensive and require huge work forces. The meson experiment involves 700 physicists from 61 institutions and 13 countries.
Fermilab physicists are now more hopeful they may be able to find signs of even more elusive particles, such as the Higgs particle, which imbues matter with mass. Without the Higgs, it is theorized, matter would have no weight.
"We hope we will see either signs of the Higgs or the discovery of new physics," said University of Chicago physicist Ivan Furic, who called the new discovery "a morale booster."
"The options are still there," he said. "The Tevatron is still taking data."
"If there are unexpected types of particles that can communicate between matter and antimatter this is a very good place to find them," said team co-leader Jacobo Konigsberg, of the University of Florida. "It helps us see if there is room for even more exotic particles that can occur in nature, but they occur in such subtle ways that we are not aware of them."[/color]


I believe this is a very intresting discovery which may eventually lead to give us a sane explanation of "para"normal. How amazing!

Wow...what a discovery. How can science ever accept that there are particles more that the speed of light in our universe...have to see the reactions of other scientists ..

Yeah, that's great! Mesons have always seemed unusual.
