text: In particle physics , CP violation is a violation of the postulated CP-symmetry : the combination of C-symmetry ( charge conjugation symmetry ) and P-symmetry ( parity symmetry ) . CP-symmetry states that the laws of physics should be the same if a particle were interchanged with its antiparticle ( C symmetry ) , and left and right were swapped ( P symmetry ) .
simplified: CP Violation is refers to the violation of C symmetry and P symmetry .
