NEW YORK In perhaps the largest single calculation ever performedby a computer, physicists at IBM have identified important propertiesof an elementary particle known as a "glueball."
The calculation required 400 million billion operations, such asadding two figures, and took a little more than two years on acomputer with 566 of the chips found in a desktop computer.
The results of the experiment, finished at IBM's Thomas J.Watson Research Center last spring, are to be published today in thejournal Physical Review Letters. It advances the understanding of a22-year-old theory on nuclear interactions known as quantumchromodynamics.
That theory supposes …
