• We discuss a natural way to generate the μ-term in the supergravity scenario. Once supergravity effects are taken into account, the vacuum expectation values (VEVs) of the heavy fields are in general shifted from their values in the supersymmetric limit. We note that this fact is independent of any Kahler ansatz, and the values of the VEV shifts are of the order of the gravitino mass. As an example, an explicit model is presented, in which both the μ-term and the B-term of the electroweak scale are generated by the VEV shifts through the supergravity effects. This model is a kind of next-to-minimal supersymmetric standard model, but there is no light standard model singlet field. Also, we emphasize that our discussion can be naturally applied to supersymmetric grand unified theory.
