...next most powerful electron accelerator, should produce new and revealing glimpses of the subatomic world by their reactions with atomic nuclei. SLAC has also been designed for the eventual addition of another 715 klystrons, which would increase its energy level to 40 BEV, exceeding even the output of Brookhaven National Laboratory's 33 BEV proton-accelerating synchrotron, currently the world's most powerful accelerator...
...experiment involved infinitesimal particles of matter so slight and evanescent that they survived only a billionth of a billionth of a second. In their place they left still lighter particles that made fine lines across a bubble chamber at Brookhaven National Laboratory. And in those curving tracks scientists traced the possibility of trouble for vast and sweeping theories that involve not only tracks in bubble chambers and bits of atoms, but also distant stars and still undiscovered galaxies...
...Brookhaven experiment involved a fast-decaying subatomic particle known as an eta meson, which breaks down into three lighter particles known as pions-one with no electrical charge. According to the theory of symmetry, the positive and negative pions should not have shown any significant difference in speed. But 53% of the time, the positive pion zipped across the bubble chamber with more energy than its negative antiparticle...
...there is an equal and opposite bit of antimatter somewhere in the universe. In the world of antimatter, all particles would be the exact mirror image of their material selves, except that their electrical charges and magnetic poles would be reversed. And it was this that the experiment at Brookhaven called into question. For if it had been done in an antimatter world, the faster positive pion would have been negatively charged. The theoretical symmetry of matter and antimatter would not hold...
This was just what Columbia's Dr. Paolo Franzini had in mind when he went to work with Brookhaven's synchrotron in January 1965. Along with his wife, Dr. Juliet Lee-Franzini, Drs. Charles Baltay and Lawrence Kirsch, he fired particles called pi mesons into a bubble chamber filled with liquid deuterium. About one-thirtieth of the times that a pi meson hit a deuterium nucleus, out came the eta meson, which decays into three pions. The pions streaked through the bubble chamber, the positive leaving a line that curved to the right, the negative peeling...
