The role of radiative corrections on an extradimensional SUSY model

TL;DR

This paper explores how radiative corrections induce supersymmetry breaking in an extra-dimensional Wess-Zumino model, using a novel mechanism involving effective operators and Kaluza-Klein excitations.

Contribution

It introduces a new approach to supersymmetry breaking via radiative corrections in an extra-dimensional model with effective operators.

Findings

Supersymmetry is explicitly broken for Kaluza-Klein modes.

Radiative corrections transmit supersymmetry breaking to the zero mode.

The model offers an alternative to geometric supersymmetry breaking mechanisms.

Abstract

Theories with extra-dimensional coordinates provide interesting mechanisms to achieve the rupture of symmetries. Here we present a novel alternative to the usual geometric considerations to achieve supersymmetric breaking for an extra-dimensional Wess-Zumino model. A supersymmetric model is constructed where the superpotential contains an effective supersymmetric non renormalizable operator, which generates, after compactification, the explicitly rupture of supersymmetry for the excited Kaluza-Klein excitations. The supersymmetry breaking is, in turn, communicated, by the radiatives corrections, to the zero mode.
