文摘The CP transformation combines charge conjugation C with parity P. Under C, particles and antiparticles are interchanged, by conjugating all internal quantum numbers, e.g., Q →Q for electromagnetic charge. Under P, the handedness of space is reversed, x^→→ -x^→. Thus, for example, a left-handed electron eL is transformed under CP into a right-handed positron, eR^＋.
