CPT theorem
From Wikipedia, the free encyclopedia
In quantum field theory, a branch of physics, the CPT theorem states that any canonical (that is, local and Lorentz-covariant) quantum field theory is invariant under the CPT operation, which is a combination of three discrete transformations: charge conjugation C, parity transformation P, and time reversal T. It was first proved by G.Lüders,[1] W.Pauli[2] and J.Bell[3] in the framework of Lagrangian field theory.
At present, CPT is the sole combination of C, P, T observed as an exact symmetry of nature at the fundamental level.[4]
