Phenomenology of unusual top partners in composite Higgs models

TL;DR

This paper explores the unique phenomenology of unconventional top partners in a composite Higgs model, including color octets and singlets, with implications for LHC searches and dark matter.

Contribution

It introduces a composite Higgs model featuring novel top partner representations, expanding the scope of possible collider signatures and dark matter candidates.

Findings

Color octet top partners could mimic gluinos at the LHC.

Color singlet top partners may serve as dark matter candidates.

Distinctive signatures help differentiate these states from supersymmetric particles.

Abstract

We consider a particular composite Higgs model which contains SU(3) color octet top partners besides the usually considered triplet representations. Moreover, color singlet top partners are present as well which can in principle serve as dark matter candidates. We investigate the LHC phenomenology of these unusual top partners. Some of these states could be confused with gluinos predicted in supersymmetric models at first glance.
