EQUIVALENCE PRINCIPLE, CP VIOLATIONS, AND THE HIGGS-LIKE BOSON MASS

We consider the violation of the equivalence principle induced by a massive gravivector, i.e., the partner of the graviton in N > 1 supergravity. The present limits on this violation allow us to obtain a lower bound on the vacuum expectation value of the scalar field that gives the gravivector its mass. We consider also the effective neutral kaon mass difference induced by the gravivector and compare the result with the experimental data on the CP-violation parameter epsilon.
