...senior research scientist at the U.S. Army Medical Research Institute of Infectious Diseases: "If you're a monkey imported from the Philippines, your first stop when you hit this country is a quarantine facility. If you're a free-ranging adult human being, you just go through the metal detector and you're on your...
Brandenburg, Huth and Professor of Physics Melissa Franklin helped design the three story high 5,000-ton detector which recorded the quarks emitted...
...Michigan physicist Myron Campbell, "and to find them, we have to process a haystack every second." During the last experimental run, for instance, a trillion collisions between protons and antiprotons occurred inside CDF's big particle trap. Yet of these, only 16 million were deemed promising enough by the detector's electronic gate-keepers to be worth more detailed analysis. Further winnowing occurred as banks of computers examined myriad measurements associated with each collision, flagging only the most interesting. Out of all this, a dozen candidates for the top emerged. "If collisions were dollars, it's like starting with...
...search for the top quark taught its hunters the true meaning of the word marathon. "This has been a part of my life for so long," says Harvard University physicist John Huth, "that there's a sense of exhaustion." The time scientists once spent working with the detector is now consumed by meetings, some 20 a week.When the CDF team comes together, it is so large it must convene in the Fermilab auditorium, and the result sometimes resembles pandemonium. The 152-page paper reporting evidence for the top quark was sent off to the Physical Review two weeks...
...remember that odds that seem like a sure bet at a racetrack are not enough to support scientific claims. Over the coming months, the lingering uncertainty that surrounds last week's announcement should be dispelled as more data are collected, not just by CDF but by a rival detector that goes by the name of DZero. If the top really is out there, as most physicists believe, then it will gradually come into focus. If not, even greater excitement will ensue. For if the top quark is not creating those bursts of particles deep inside the detector, then what...
