Also, we can define the strange antimatter as formed by a large number of antiquarks bound together with an antielectron
Anderson had found the positively charged particle that Dirac had predicated--the antielectron
An atom of unmatter is formed either by (1): electrons, protons, and antineutrons, or by (2): antielectrons
, antiprotons, and neutrons.
This concept calls for a machine to collide electrons and positrons, also known as antielectrons
, headon at energies similar to that of the LHC.
The experiment captures antiprotons and combines them with antielectrons
(positrons) to make antihydrogen atoms, which are stored and studied for a few seconds in a magnetic trap.
The negatively charged antiprotons that Segre discovered in 1955 pair very nicely with antielectrons
) were sensed by Fermi's Gamma-ray Burst Monitor (GBM) coming from "terrestrial gamma-ray flashes" that occur above thunderstorms.
Also we can define a mesonic antiatom as an ordinary antiatomic nucleous with one or more of its antielectrons
replaced by positively-charged mesons.
The achievement represents an important step toward creating the antimatter counterpart of hydrogen by merging beams of antiprotons and antielectrons
, or positrons.
