[ILLUSTRATION OMITTED] Researchers at Fermilab's DZero detector, which smashes together protons and antiprotons circling almost at light speed in the Tevatron accelerator, took about a year to sift through data gathered between 2002 and 2006.
Concerned with antiproton beams with kinetic energies of order keV or less, the papers delve into such topics as CPT symmetry and gravitation, the structure of exotic nuclei, atomic collisions, and atom physics in general, with particular focus on recent advances in manipulating large numbers of ultra-slow antiprotons and synthesizing antihydrogen atoms.
Untold numbers of electrons and positrons, protons and antiprotons, neutrons and antineutrons canceling each other out, leaving behind the small residue of protons, neutrons and electrons that today form the Earth, the solar system, and all the galaxies in the universe.
