CP Violation and Cosmological Fields
The rather surprising fact that the decay properties of the neutral K mesons can provide information on the gravitational interaction of these particles was first discovered by Good  long before CP violation. He realized that the very observation of a short and long lived component implied that the gravitational energies of KO and ̄KO could not be very different. So the ̄KO cannot fall upwards as was proposed sometimes for antiparticles. The discovery of CP violation  brought increased interest to this field. A number of suggestions were made to explain the observed CP violation by the action of some unknown cosmological field –. Most of these explanations have now been ruled out by experiment. But we can take another point of view, as Professor Thirring did last year here in Schladming , namely to ask what information we can get from existing experiments on cosmological fields. We will explore this below in a simple field theoretical model. But before we will review the propagator method for defining the mass matrix as given by Sachs , .
