SUSY Breaking from Exotic U(1)

TL;DR

This paper introduces a novel five-dimensional mechanism where dynamical rearrangement of an exotic U(1) symmetry induces soft supersymmetry breaking masses, featuring unique eigenstate and charge properties.

Contribution

It presents a new approach to SUSY breaking via local U(1) symmetry dynamics with unusual features in eigenstates and charge assignments.

Findings

Eigenstates of U(1) differ from boundary condition eigenstates

Standard model particles and superpartners have different U(1) charges

A large U(1) charge hierarchy yields TeV-scale masses

Abstract

We propose a mechanism that the soft supersymmetry breaking masses can be induced from the dynamical rearrangement of local U(1) symmetry in a five-dimensional model. The U(1) symmetry possesses several extraordinary features. The eigenstates of U(1) do not equal to those of boundary conditions. The U(1) charge of standard model particles does not equal to that of superpartners. A large U(1) charge hierarchy among superpartners and a standard model gauge singlet is necessary in order to obtain the masses of O(1)TeV.
