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 ...

The light composite Higgs boson in strong extended technicolor [PDF]
Journal of High Energy Physics, 2017 This paper extends an earlier one describing the Higgs boson H as a light composite scalar in a strong extended technicolor model of electroweak symmetry breaking. The Higgs mass M H is made much smaller than ΛETC by tuning the ETC coupling very close to

LHC lifetime frontier and visible decay searches in composite asymmetric dark matter models [PDF]
Journal of High Energy Physics, 2022 The LHC lifetime frontier will probe dark sector in near future, and the visible decay searches at fixed-target experiments have been exploring dark sector.

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.

Relaxation of the composite Higgs little hierarchy
Journal of High Energy Physics, 2017 We describe a composite Higgs scenario in which a cosmological relaxation mechanism naturally gives rise to a hierarchy between the weak scale and the scale of spontaneous global symmetry breaking.

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.

Testing a dynamical origin of Standard Model fermion masses [PDF]
, 2016 We discuss a test of the Standard Model fermion mass origin in models of dynamical electroweak symmetry breaking. The couplings of composite pseudoscalar resonances to top quarks allow to distinguish high-scale Extended-Technicolor-type fermion mass ...
