Top Signatures From Composite Higgs Theories

TL;DR

This paper discusses how composite Higgs models predict new strongly-interacting states that primarily couple to top quarks, leading to distinctive collider signatures involving top quarks for testing these theories at the LHC and future colliders.

Contribution

It identifies key signatures involving top quarks that can be used to discover or test minimal composite Higgs models at collider experiments.

Findings

New composite states interact mainly with third-generation quarks.

Signatures involving top quarks are promising for collider searches.

Potential for discovery at LHC and future colliders.

Abstract

Many compelling theories to address the Higgs hierarchy problem predict strong interactions between the top and a sector of New Physics. In minimal composite Higgs models (CHM), the top interactions with a BSM strongly-interacting sector give the leading contribution to trigger the EWSB and generate a light mass for the pseudo-NG Higgs. This implies that new composite states (vector-like top-partners, composite vector resonances, new composite scalars) dominantly interact with third-generation quarks and, when produced at colliders, generate top quarks in the final state. I will indicate interesting signatures involving top quarks for CHM discovery/test at the LHC and future colliders.
