CPTsymmetry
CPTsymmetry refers to a fundamental symmetry in physics that combines charge conjugation (C), parity inversion (P), and time reversal (T). Charge conjugation (C) is the operation of swapping all particles with their antiparticles. Parity inversion (P) is the operation of inverting all spatial coordinates, essentially creating a mirror image. Time reversal (T) is the operation of reversing the direction of time.
The CPT theorem states that any physical theory that is Lorentz invariant and satisfies locality must be
While individual C, P, and T symmetries are known to be violated in certain particle interactions (most
