An almost elementary Higgs: theory and practice
Journal of High Energy Physics, 2018 We study models that interpolate between an elementary and a composite Higgs boson. Such models, arising in theories with new vector-like fermions with electroweak quantum numbers and charged under a confining gauge interaction, are entirely compatible ...

Real and complex fundamental partial compositeness
Journal of High Energy Physics, 2020 We complete the analysis of the effective field theory at the electroweak scale for minimal models of fundamental partial compositeness. Specifically, we consider fermions in the complex and real representation of the gauge group underlying the composite

Probing the top-Higgs sector with composite Higgs models at present and future hadron colliders
Journal of High Energy Physics, 2021 We study the production of t t ¯ h $$ t\overline{t}h $$ and t t ¯ hh $$ t\overline{t} hh $$ at hadron colliders, in the minimal Composite Higgs Models, based on the coset SO(5)/SO(4). We explore the fermionic representations 5 and 14.

Neutrino masses from low scale partial compositeness
Journal of High Energy Physics, 2021 We consider a class of models in which the neutrinos acquire Majorana masses through mixing with singlet neutrinos that emerge as composite states of a strongly coupled hidden sector.

Gravitational Techniwaves [PDF]
, 2010 We investigate the production and possible detection of gravitational waves stemming from the electroweak phase transition in the early universe in models of minimal walking technicolor.

Very light dilaton and naturally light Higgs boson
Journal of High Energy Physics, 2018 We study very light dilaton, arising from a scale-invariant ultraviolet theory of the Higgs sector in the standard model of particle physics. Imposing the scale symmetry below the ultraviolet scale of the Higgs sector, we alleviate the fine-tuning ...

The Electroweak Phase Transition in Ultra Minimal Technicolor
, 2009 We unveil the temperature-dependent electroweak phase transition in new extensions of the Standard Model in which the electroweak symmetry is spontaneously broken via strongly coupled, nearly-conformal dynamics achieved by the means of multiple matter ...

Constraining scalar resonances with top-quark pair production at the LHC
Journal of High Energy Physics, 2018 Constraints on models which predict resonant top-quark pair production at the LHC are provided via a reinterpretation of the Standard Model (SM) particle level measurement of the top-anti-top invariant mass distribution, m t t ¯ $$ m\left(t\overline{t ...

Minimal Super Technicolor [PDF]
, 2011 We introduce novel extensions of the Standard Model featuring a supersymmetric technicolor sector. First we consider N=4 Super Yang-Mills which breaks to N=1 via the electroweak (EW) interactions and coupling to the MSSM.
