To be (finite) or not to be, that is the question "Kaluza-Klein contribution to the Higgs mass"

TL;DR

This paper analyzes how a specific regularization scheme in five-dimensional supersymmetric models influences the finite one-loop correction to the Higgs mass, highlighting the scheme's role in the predicted Higgs mass.

Contribution

It demonstrates that the finite Higgs mass correction in these models is a result of a particular Kaluza-Klein regularization scheme, clarifying the origin of the prediction.

Findings

Finite one-loop Higgs mass correction depends on Kaluza-Klein regularization.

The predicted Higgs mass is a consequence of the regularization scheme used.

The regularization scheme leads to a finite and definite Higgs mass prediction.

Abstract

Recently five dimensional supersymmetric models with a Scherk-Schwarz supersymmetry breaking and a localized superpotential on a fixed-point have been constructed to yield a definite prediction for the Higgs mass. We examine this issue in detail and show that the finite one loop correction and the definite prediction for the Higgs mass are just a consequence of a special "Kaluza-Klein regularization" scheme.
