laengpariteetsümmeetria
Laengpariteetsümmeetria, often abbreviated as CP-sümmeetria, refers to a fundamental concept in particle physics that combines charge conjugation (C) and parity transformation (P). Charge conjugation is an operation that flips the sign of all internal quantum numbers of a particle, effectively transforming a particle into its antiparticle. Parity transformation, on the other hand, is a spatial inversion, which reflects the spatial coordinates through the origin. CP-sümmeetria posits that the laws of physics remain unchanged if a particle is simultaneously replaced by its antiparticle and its spatial coordinates are inverted.
Historically, it was believed that both charge conjugation (C) and parity (P) symmetries were independently conserved
The observation of CP-violation in the decay of neutral kaons in 1964 was a significant discovery. This
