No references found			These particles in turn radiate more photons, which create more electron-positron pairs. Probing the heart of extragalactic jets by Cowen, Ron / Science News The presence of a pair of mirrors modifies the vacuum so that certain types of interactions between photons and the phantom electron-positron pairs can no longer occur. Secret of the vacuum: speedier light by Science News The experimenters now suppose that some new subatomic particle, electrically neutral with a mass three to four times that of the electron, is produced in these nucleus-nucleus collisions, and it then decays to an electron-positron pair.
