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 ...

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.

Vacuum alignment in composite technicolor standard models [PDF]
Physics Letters, Section B: Nuclear, Elementary Particle and High-Energy Physics, 1992 Abstract We consider the question of vacuum alignment in the recently proposed “composite technicolor standard models” (CTSMs). In these models, explicit chiral symmetry breaking due to masses of electroweak-singlet “ultrafermions” is communicated to the quarks and leptons by a chiral condensate produced by strong “ultracolor” gauge interactions.

The light composite Higgs boson in strong extended technicolor
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

A composite technicolor standard model of quarks
Nuclear Physics B, 1987 Abstract We discuss the difficulties with anomaly constraints and flavor breaking involved in building a composite technicolor standard model. We construct a model of quarks with the required symmetry properties.

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.

Composite-technicolor standard model
Physics Letters, Section B: Nuclear, Elementary Particle and High-Energy Physics, 1987 Abstract We characterize a class of composite models in which the quarks and leptons and technifermions are built from fermions (preons) bound by strong gauge interactions. We argue that if the preon dynamics has as [SU(3) × U(1)]5 flavor symmetry that is explicitly broken only by preon mass terms proportional to the quark and lepton mass matrices ...

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

Flavor changing neutral currents in a realistic composite technicolor model [PDF]
Physics Letters B, 1993 We consider the phenomenology of a composite technicolor model proposed recently by Georgi. Composite technicolor interactions produce four-quark operators in the low energy theory that contribute to flavor changing neutral current processes. While we expect operators of this type to be induced at the compositeness scale by the flavor-symmetry breaking

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 ...
