We define a Majorana field as an eigenstate of charge conjugation.

In the language of quantum field theory, charge conjugation transforms:

Certain subatomic interactions involving the weak nuclear force violate the conservation of both Parity (physics) and charge conjugation, but only very rarely.

The CP violation (charge conjugation and parity) was established in the neutral kaon system in 1964.

In this theorem, regarded as one of the basic principles of quantum field theory, charge conjugation, parity, and time reversal are applied together.

It is suitable when the symmetries of charge conjugation, time reversal symmetry, and parity are good.

Since G-parity is applied on a whole multiplet, charge conjugation has to see the multiplet as a neutral entity.

To preform a charge conjugation, one would exchange all particles with their corresponding antiparticles.

Parity, charge conjugation and time reversal symmetry.

A left-handed neutrino would be taken by charge conjugation into a left-handed antineutrino, which does not interact in the Standard Model.
