CPTtétel
CPT-tétel is a fundamental result in quantum field theory stating that any local, Lorentz-invariant quantum field theory with a stable vacuum and a Hermitian Hamiltonian is invariant under the combined CPT transformation, where C denotes charge conjugation, P parity transformation, and T time reversal. The theorem implies the existence of a CPT operator that is antiunitary, and it asserts that the theory’s S-matrix is unchanged under the application of CPT.
The precise statement is that, under the stated assumptions, the laws of physics do not distinguish a
Historically, the CPT theorem was established in the 1950s within the framework of axiomatic or Wightman quantum
Experimentally, CPT invariance has been tested extensively. Comparisons of masses, lifetimes, and other properties of particles
