Abstract
We recall the meanings of the fundamental C, P and T transformations of basic processes. Charge conjugation C consists of replacing every particle in a given process by its anti-particle, while parity transformation P, also referred to as space reflection, consists in considering a given process as reflected through the origin of a coordinate system and involves the reversal of the direction of the three-momentum of every particle as well as of the consideration of their intrinsic parities.

CP violation is also observed in the B-meson system, see, Aubert et al. [2]; Chao et al. [3]. CP violation has been also considered in baryon decay which would indicate an asymmetry in the decay rate of baryon and an anti-baryon: LHCb collaboration [11]. See also the paper by Durieux and Grossman [6] which may be relevant in understanding of the matter-antimatter imbalance in the Universe.
