The top quark mass in the minimal top condensation model with extra dimensions

TL;DR

This paper explores how extra dimensions influence top quark mass predictions in a minimal top condensation model, showing that gauge and Yukawa coupling evolution can align theoretical predictions with experimental data at accessible energy scales.

Contribution

It demonstrates that incorporating large extra dimensions modifies the BHL model, allowing for realistic top quark mass predictions at relatively low cut-off scales.

Findings

Top quark mass predictions are lowered due to extra dimensions.

Gauge and Yukawa couplings evolve with power-law behavior.

Experimental top mass values can be achieved at a few TeV scale.

Abstract

The minimal dynamical electroweak symmetry breaking through top condensation in the presence of compact large extra dimensions is studed. It is shown that thanks to the power-low evolution of gauge and Yukawa couplings the original BHL predictions for the top quark mass are significantly lowered and even for small cut-off scale $\Lambda \sim few$ TeV one can obtain experimentally allowed values.
