- | Formulated differently, the CPT theorem says that any Lorentz invariant local [[theories:quantum_field_theory|quantum field theory]] with a Hermitian Hamiltonian must be CPT symmetric. | + | Formulated differently, the CPT theorem says that any Lorentz invariant local [[theories:quantum_field_theory:canonical|quantum field theory]] with a Hermitian Hamiltonian must be CPT symmetric. |

From these assumptions it follows that the Lagrangian is also invariant under the produce of C, P, and T , taken in any order. Take note that $C$, $P$, $T$ or any other product of them can be violated, which CPT is intact. This means concretely that we can always choose the phases which appear in C, P, T transformations such that the product of those operators is a symmetry of our theory. | From these assumptions it follows that the Lagrangian is also invariant under the produce of C, P, and T , taken in any order.
