CP violation refers to the phenomenon where the combined operations of charge conjugation (C) and parity (P) do not yield the same physics for certain processes. Charge conjugation transforms a particle into its antiparticle, while parity transformation involves flipping the spatial coordinates (like mirroring). In essence, if a physical process behaves differently when particles are swapped for antiparticles (C transformation) and mirrored (P transformation), then CP violation is occurring.
