$\mu$ Parameter from Dynamical Rearrangement of U(1) and $\theta$ Parameter

TL;DR

This paper explores how the $$ parameter can be dynamically generated through local U(1) symmetry rearrangement in a five-dimensional framework, analyzing implications for the $ heta$ parameter with supersymmetry breaking via Scherk-Schwarz mechanism.

Contribution

It introduces a novel mechanism for generating the $$ parameter through dynamical rearrangement in higher dimensions, linking it to phenomenological effects on the $ heta$ parameter.

Findings

Demonstrates a new dynamical origin for the $$ parameter.

Analyzes the impact on the $ heta$ parameter under supersymmetry breaking.

Provides phenomenological implications of the mechanism.

Abstract

We study the generation of $\mu$ parameter from the dynamical rearrangement of local U(1) symmetry in a five-dimensional model and discuss phenomenological implications on the $\theta$ parameter, under the assumption that supersymmetry is broken by the Scherk-Schwarz mechanism.
