Higgs Production via Gluon Fusion in a Six Dimensional Universal Extra Dimension Model on S^2/Z_2

TL;DR

This paper predicts a significant enhancement in Higgs boson production via gluon fusion at the LHC within a six-dimensional universal extra dimension model compactified on S^2/Z_2, compared to the Standard Model.

Contribution

It introduces a six-dimensional universal extra dimension model on S^2/Z_2 and calculates its impact on Higgs production cross section at the LHC.

Findings

Higgs production cross section is predicted to be 30% higher than the Standard Model.

The enhancement is about 10% compared to the minimal universal extra dimension model.

The results are for a compactification scale around 1 TeV.

Abstract

We investigate Higgs boson production process via gluon fusion at LHC in our six dimensional universal extra dimension model compactified on a spherical orbifold S^2/Z_2. We find a striking result that Higgs production cross section in our model is predicted to be 30(10)% enhancement comparing to the predictions of the Standard Model (the minimal universal extra dimension model) for the compactification scale of order 1 TeV.
