Particle-antiparticle pairs can annihilate each other, producing photons ; since the charges of the particle and antiparticle are opposite, total charge is conserved.
The remarkable notion of an antiparticle to each fermion particle – e.g. the positron as antiparticle to the electron – stems from his equation.
A possible mechanism points to the existence of heavy neutrinos that were its own antiparticle, and therefore, could decay into both matter and antimatter.
Solving this problem has implications for understanding the early universe’s behavior, whether the neutrino is its own antiparticle, and why there’s more matter than antimatter in the universe.
Antineutrinos are another kind of antiparticle created by natural radioactivity (β − decay).
Antineutrinos are another kind of antiparticle produced by natural radioactivity (β − decay).

As the Universe expanded and cooled, the average thermal energy of these lighter particles decreased and eventually became insufficient to form a dark matter particle-antiparticle pair.

C-parity main C-parity is only defined for mesons that are their own antiparticle (i.e. neutral mesons).
Each baryon has a corresponding antiparticle (antibaryon) where quarks are replaced by their corresponding antiquarks.
Each Feynman diagram is the sum of exponentially many old-fashioned terms, because each internal line can separately represent either a particle or an antiparticle.
