CP invariance
CP invariance C5743950 (sē′pē′)n. In particle physics, a form of invariance in which reversing all spatial dimensions and the sign of all charges in the description of a physical system results in an indistinguishable physical system. CP invariance does not appear to hold in nature, as evidenced by the decay of kaons. Also called charge parity invariance.

CP invariance[¦sē¦pē in′ver·ē·əns] (particle physics) The principle that the laws of physics are left unchanged by a combination of the operations of charge conjugation C and space inversion P; a small violation of this principle has been observed in the decay of neutral K- mesons. |
