The search for a nonzero value of the electric dipole moment of the neutron is a direct test of the application of this theorem to hadrons. It is impossible to construct a quantum theory if this theorem is assumed to be violated, and a direct consequence is that each particle must have the same lifetime and mass as its antiparticle. One of the most sensitive tests of this theorem is the mass difference between a neutral kaon and its antiparticle, since only in kaons does there occur a violation of two of the three associated symmetries that this theorem addresses. FTP, identify this fundamental theorem of quantum mechanics which states that the product of time reversal, charge conjugation, and parity reversal is an exact symmetry of any interaction.  3
