WebAntimatter is in every precise meaningful sense matter moving backward in time. The notion of "moving backward in time" is nonsensical in a Hamiltonian formulation, because the whole description can only go forward in time. That's the definition of what the Hamiltonian does – it takes you forward in time a little bit. Web0 protons, 0 neutrons, 0 electrons, 1 positron. This is a beta + particle. It can also be written as e +. "e" represents an electron, but when it has as positive charge it is a positron. β-0 protons, 0 neutrons, 1 electron.
