A composite Higgs model with minimal fine-tuning: The large-
Physical Review D, 2014 We suggest a criterion to minimize the amount of fine-tuning in a composite Higgs model. The paradigm of this type of model is the top-condensate model of Bardeen, Hill and Lindner (BHL). Although "minimally fine-tuned", this model failed to account correctly for the masses of the top quark and the 125~GeV Higgs boson.

Composite Higgs models, Technicolor and the muon anomalous magnetic moment
Physics Letters B, 2016 We revisit the muon magnetic moment (g−2) in the context of Composite Higgs models and Technicolor, and provide general analytical expressions for computing the muon magnetic moment stemming from new fields such as, neutral gauge bosons, charged gauge ...

Large Higgs quartic coupling and (A)DM from extended bosonic Technicolor
Physics Letters B, 2021 We propose novel bosonic Technicolor models augmented by an SU(2)R gauge group and scalar doublet. Dynamical breaking of SU(2)R induced by technifermion condensation triggers SU(2)L breaking via a portal coupling. The scale of the new strong interactions

Phenomenology of unusual top partners in composite Higgs models
Journal of High Energy Physics, 2022 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 ...

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 ...

Light composite scalar boson from a see-saw mechanism in two-scale TC models
Physics Letters B, 2015 We consider the possibility of a light composite scalar boson arising from mass mixing between a relatively light and heavy scalar singlets in a see-saw mechanism expected to occur in two-scale Technicolor (TC) models.

Dark matter in (partially) composite Higgs models
Journal of High Energy Physics, 2018 We construct composite and partially composite Higgs models with complex pseudo-Nambu-Goldstone (pNGB) dark matter states from four-dimensional gauge-Yukawa theories with strongly interacting fermions.

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
