Limit on Higgs boson trilinear self-coupling in coupled technicolor models

, 2022
The trilinear self-coupling of the Higgs boson, in a theory in which this boson is composite, is compared to the experimental bound of this quantity obtained by the CMS experiment.

Composite Higgs at high transverse momentum

Journal of High Energy Physics, 2020
In this paper we explore composite Higgs scenarios through the effects of light top-partners in Higgs+Jet production at the LHC. The pseudo-Goldstone boson nature of the Higgs field means that single-Higgs production via gluon fusion is insensitive to ...

Discovering Technicolor [PDF]

, 2011
We provide a pedagogical introduction to extensions of the Standard Model in which the Higgs is composite. These extensions are known as models of dynamical electroweak symmetry breaking or, in brief, Technicolor.

Phenomenology of flavorful composite vector bosons in light of B anomalies

Journal of High Energy Physics, 2017
We analyze the flavor structure of composite vector bosons arising in a model of vectorlike technicolor — often called hypercolor (HC) — with eight flavors that form a one-family content of HC fermions.

A more natural composite Higgs model

Journal of High Energy Physics, 2020
Composite Higgs models provide an attractive solution to the hierarchy problem. However, many realistic models suffer from tuning problems in the Higgs potential. There are often large contributions from the UV dynamics of the composite resonances to the

The present and future of four top operators

Journal of High Energy Physics, 2021
We study the phenomenology of a strongly-interacting top quark at future hadron and lepton colliders, showing that the characteristic four-top contact operators give rise to the most significant effects.

Technicolor walks at the LHC [PDF]

, 2009
We analyze the potential of the Large Hadron Collider (LHC) to observe signatures of phenomenologically viable walking technicolor models. We study and compare the Drell-Yan and vector boson fusion mechanisms for the production of composite heavy vectors.

Techni-Composite Higgs models with (a)symmetric dark matter candidates [PDF]

, 2021
We propose a novel class of composite models that feature both a technicolor and a composite Higgs vacuum limit, resulting in an asymmetric dark matter candidate.

Minimally extended SILH

Journal of High Energy Physics, 2017
Higgs boson compositeness is a phenomenologically viable scenario addressing the hierarchy problem. In minimal models, the Higgs boson is the only degree of freedom of the strong sector below the strong interaction scale.

Searches for vector-like quarks at future colliders and implications for composite Higgs models with dark matter

Journal of High Energy Physics, 2018
Many composite Higgs models predict the existence of vector-like quarks with masses outside the reach of the LHC, e.g. m Q ≳ 2 TeV, in particular if these models contain a dark matter candidate.
