Constrained Standard Model from Extra Dimension

TL;DR

This paper constructs a five-dimensional supersymmetric model that naturally predicts the Higgs mass and superparticle spectrum, including a light top squark, with finite radiative corrections and detailed physical explanations.

Contribution

It introduces a novel five-dimensional supersymmetric framework that yields finite Higgs potential corrections and specific predictions for superparticle masses.

Findings

Higgs mass predicted as 127 ± 8 GeV

Lightest superparticle is a top squark of 197 ± 20 GeV

Radiative corrections to Higgs potential are finite and calculable

Abstract

A five dimensional supersymmetric model is constructed which reduces to the one Higgs-doublet standard model at low energies. The radiative correction to the Higgs potential is finite and calculable, allowing the Higgs mass prediction of 127 \pm 8 GeV. The physical reasons for this finiteness are discussed in detail. The masses of the superparticles and the Kaluza-Klein excitations are also predicted. The lightest superparticle is a top squark of mass 197 \pm 20 GeV.
