Radiative correction to the lightest neutral Higgs mass in warped supersymmetry

TL;DR

This paper calculates how Kaluza-Klein towers in warped supersymmetry models can significantly increase the upper limit of the lightest neutral Higgs mass, impacting predictions in particle physics.

Contribution

It provides the first detailed computation of KK-induced radiative corrections to the Higgs mass in warped supersymmetric models.

Findings

KK corrections can raise the Higgs mass limit by up to 100 GeV.

The correction depends on extra-dimensional parameters and the fermion mass hierarchy.

The results suggest a broader parameter space for Higgs mass predictions in warped SUSY.

Abstract

We compute radiative correction to the lightest neutral Higgs mass ($m_h$) induced by the Kaluza-Klein (KK) towers of fermions and sfermions in a minimal supersymmetric scenario embeded in a 5-dimensional warped space. The Higgs is confined to the TeV brane. The KK spectra of matter supermultiplets is tied to the explanation of the fermion mass hierarchy problem. We demonstrate that for a reasonable choice of extra-dimensional parameters, the KK-induced radiative correction can enhance the upper limit on $m_h$ by as much as 100 GeV beyond the 4d limit of 135 GeV.
