In one reaction, D plus and D minus mesons are produced when this particle collides with its matter counterpart.
In one reaction, D plus and D minus mesons are produced when this particle collides with its matter counterpart. Paul Dirac postulated their existence in 1930 to account for the otherwise superfluous negative energy states of the electron that were predicted by his relativistic quantum theory. FTP, name the particle discovered in 1932 by Carl Anderson, the antiparticle of the electron.
