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

TL;DR

This paper introduces a five-dimensional model where the soft supersymmetry breaking masses and the $$ parameter are generated through the dynamical rearrangement of local U(1) symmetries, potentially solving the $$ problem.

Contribution

It presents a novel mechanism linking extra-dimensional U(1) symmetry dynamics to supersymmetry breaking parameters, offering a new approach to the $$ problem.

Findings

Demonstrates how the dynamical rearrangement induces soft SUSY breaking masses.

Shows the $$ parameter can be generated from U(1) symmetry dynamics.

Provides conditions under which the hierarchy among U(1) charges stabilizes the mechanism.

Abstract

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.
