C-symmetry
SYMMETRY OF PHYSICAL LAWS UNDER A CHARGE-CONJUGATION TRANSFORMATION
Charge conjugation; Charge Conjugation; C symmetry; Charge conjugation parity; Charge conjugation symmetry
In physics, charge conjugation is a transformation that switches all particles with their corresponding antiparticles, thus changing the sign of all charges: not only electric charge but also the charges relevant to other forces. The term C-symmetry is an abbreviation of the phrase "charge conjugation symmetry", and is used in discussions of the symmetry of physical laws under charge-conjugation.
