A Light Scalar in Low-Scale Technicolor

TL;DR

This paper explores the properties and potential discovery channels of a light scalar particle, $\sigma_T$, in low-scale technicolor models, highlighting its similarities to a heavy Higgs boson and its detectability at the LHC.

Contribution

It introduces the $\sigma_T$ scalar in low-scale technicolor and analyzes its production and decay modes relevant for LHC detection.

Findings

$\sigma_T$ is a narrow isoscalar scalar in 200-700 GeV range.

It behaves like a heavy Higgs with a small vev.

Potential for discovery via weak boson fusion at the LHC.

Abstract

In addition to the narrow spin-one resonances $\rho_T$, $\omega_T$ and $a_T$ occurring in low-scale technicolor, there will be relatively narrow scalars in the mass range 200 to 600--700 GeV. We study the lightest isoscalar state, $\sigma_T$. In several important respects it is like a heavy Higgs boson with a small vev. It may be discovered with high luminosity at the LHC where it is produced via weak boson fusion and likely has substantial $W^+ W^-$ and $Z^0Z^0$ decay modes.
