Field theory as a tool to constrain new physics models
, 2015 One of the major problems in developing new physics scenarios is that very often the parameters can be adjusted such that in perturbation theory almost all experimental low-energy results can be accommodated.

Journal of High Energy Physics, 2022 We investigate radiatively stable classes of pseudo-Nambu-Goldstone boson (pNGB) potentials for approximate spontaneously broken SO(N + 1) → SO(N). Using both the one-loop effective action and symmetry, it is shown that a Gegenbauer polynomial potential ...

Limit on the fermion masses in technicolor models [PDF]
, 2003 Recently it has been pointed out that no limits can be put on the scale of fermion mass generation $(M)$ in technicolor models, because the relation between the fermion masses $(m_f)$ and $M$ depends on the dimensionality of the interaction responsible ...

A concrete composite 2-Higgs doublet model
Journal of High Energy Physics, 2018 We consider a Composite Higgs Model (CHM) with two isospin doublet Higgs fields arising as pseudo Nambu-Goldstone bosons from a SO(6) → SO(4) × SO(2) breaking.

Composite Higgs revealed in Higgs pair photo-production at future colliders
Journal of High Energy Physics, 2021 The next generation electron-positron colliders are designed for precision studies of the Standard Model and its extensions, in particular in the Higgs sector.

, 2010 We consider a supersymmetric QCD with soft supersymmetry breaking terms as the dynamics for the electroweak symmetry breaking. We find various advantages compared to the non-supersymmetric models, such as a natural incorporation of the dynamical top ...

Strong Interactive Massive Particles from a Strong Coupled Theory [PDF]
, 2007 Minimal walking technicolor models can provide a nontrivial solution for cosmological dark matter, if the lightest technibaryon is doubly charged. Technibaryon asymmetry generated in the early Universe is related to baryon asymmetry and it is possible to

A vector leptoquark for the B-physics anomalies from a composite GUT
Journal of High Energy Physics, 2019 A vector leptoquark at the TeV scale, mostly coupled to the fermions of the third generation, is the preferred option to explain the hints of lepton flavor universality violation in the decays of B-mesons.

Composite Higgs and leptoquarks from a simple group
Journal of High Energy Physics, 2019 We propose a composite grand unified theory to study the anomalies in the semileptonic B decays. We show a simple group containing the custodial and Standard Model gauge symmetries, that can deliver a set of composite pseudo Nambu-Goldstone bosons: the ...

CP-Violation in a composite 2-Higgs doublet model
Journal of High Energy Physics, 2021 We study CP-Violation (CPV) in a Composite 2-Higgs Doublet Model (C2HDM) based on the global symmetry breaking SO(6)/[SO(4) × SO(2)], wherein the strong sector is modeled by a two-site moose structure.
