...evidence comes from collisions between subatomic protons and antiprotons inside the giant Tevatron accelerator at the Fermi National Accelerator Laboratory near Chicago. The type of particle debris that spews out of such collisions tells scientists what the original particles were made of. That's how quarks were discovered in the first place...
...Tevatron is so powerful that it can probe the structure within quarks themselves--structure that had, until now, been presumed not to exist. If, as it seems, there really is something lurking inside the quark, the whole Standard Model may have to be trashed. And subatomic physics may suddenly become a lot more interesting than even its practitioners suspected...
Over one year's worth of data was collected from Fermilab's Tevatron the highest energy particle accelerator in the world...
...expanded and cooled, they all but disappeared. Now they occur naturally only under certain conditions. To conjure them up, scientists have to re-create the fiery conditions that followed the Big Bang, not an easy task. Because the top is so heavy, only the most energetic collisions in the Tevatron are capable of producing the particle at all. In addition, this king of quarks has such an infinitesimal lifetime that its presence can be inferred only from the whispery contrails of other particles into which it promptly decays. Thus the detector designed by Fermilab's scientists consists of more than...
...quarks were culled from highspeed collisions between protons and antiprotons in the Tevatron particle accelerator at Fermilab--a circular underground track four miles long which rams particles together at speeds approaching that of light...
