Possible Experiments with Antihydrogen

  • Reinhard Neumann
Part of the Ettore Majorana International Science Series book series (EMISS, volume 31)


Antihydrogen is the antimatter counterpart of hydrogen and therefore consists of an antiproton and a positron. Till now, no antihydrogen has been produced and identified at any facility in the world. Thus, formation and detection of one antihydrogen atom would be the first artificial realization of atomic neutral antimatter.
