Soft Supersymmetry Breaking Masses and μ Parameter from Dynamical Rearrangement of Exotic U(1) Symmetries

We propose a mechanism that the soft supersymmetry breaking masses and $\mu$ parameter can be induced from the dynamical rearrangement of local U(1) symmetries in a five-dimensional model. It offers to a solution of $\mu$ problem if there is a large hierarchy among the relevant U(1) charge of Higgsinos and that of hidden fields which stabilize the extra-dimensional component of U(1) gauge boson.
