[Moderator's note: CPT symmetry does not have to be taken into account.
In Lorentz-invariant quantum field theories Wolfgang Pauli *proved* that
the CPT symmetry must hold. No experimental violation of CPT is known
either. String theory goes beyond QFT, and Pauli's proof does not apply
directly. People like V. Alan Kostelecky studied a possible CPT violations
in string theory, but all these models also violate Lorentz symmetry. LM]
