What interests physicists, though, is not just what the Z 0 does but how long it lives before decaying. The precise length of its life, which is less than a trillionth of a trillionth of a second, will reveal how many sorts of particles the Z 0 decays into and thus how many other particles exist. Current theory says there may be only one fundamental particle of matter, called the top quark, left to observe. But there may be many more, and gauging the Z 0's lifetime will tell physicists how close they are to a full understanding...
...produced 120 Z 0s. That is enough to calculate the particle's mass more accurately than ever before. And by the end of the year, when the number of Z 0s produced is expected to reach 2,000, the Stanford scientists think they could have the Z 0's life expectancy pinned down. But by that time the LEP may have beaten them to the goal. "I had hoped," acknowledges Burton Richter, the Stanford center's director, "that we would be in the shape we are now in a year ago. If a miracle had happened and we'd come...
...tunnel, with new particles added periodically to the stream. In a given period of time, the LEP is expected to produce hundreds of times as many Z 0s as the Stanford collider does. That gives CERN the best odds of being the first to measure the Z 0's life-span...
...have been sold at 20 cents apiece, or 99 cents for a pack of five. On the back of each 4-in. by 6-in. card, printed in English and Hebrew, are the rabbi's dates of birth and death, the books he published and details about his life...
...Bond staples. As the main female lead, Carey Lowell provides a bit of excitement at first; she's a CIA informer for Felix whom Dalton picks up during his investigation. They narrowly escape death at their first meeting, and spend an amusing few minutes arguing over who saved whose life and who acted most professionally. Unfortunately, Lowell's role quickly degenerates to the point where she's half kept woman and half sidekick...
