Discovering Technicolor [PDF]

, 2011
We provide a pedagogical introduction to extensions of the Standard Model in which the Higgs is composite. These extensions are known as models of dynamical electroweak symmetry breaking or, in brief, Technicolor.

Technicolor walks at the LHC [PDF]

, 2009
We analyze the potential of the Large Hadron Collider (LHC) to observe signatures of phenomenologically viable walking technicolor models. We study and compare the Drell-Yan and vector boson fusion mechanisms for the production of composite heavy vectors.

The present and future of four top operators

Journal of High Energy Physics, 2021
We study the phenomenology of a strongly-interacting top quark at future hadron and lepton colliders, showing that the characteristic four-top contact operators give rise to the most significant effects.

iTIMP: isotriplet Technicolor Interacting Massive Particle as Dark Matter [PDF]

, 2010
We suggest that a weak isotriplet composite scalar possessing an unbroken U(1) global symmetry naturally arises in technicolor models leading to an interesting type of dark matter candidate: the iTIMP. We propose explicit models of the iTIMP, study earth

Minimally extended SILH

Journal of High Energy Physics, 2017
Higgs boson compositeness is a phenomenologically viable scenario addressing the hierarchy problem. In minimal models, the Higgs boson is the only degree of freedom of the strong sector below the strong interaction scale.

Limit on Higgs boson trilinear self-coupling in coupled technicolor models

, 2021
The trilinear self-coupling of the Higgs boson, in a theory in which this boson is composite, is compared to the experimental bound of this quantity obtained by the CMS experiment.

Searches for vector-like quarks at future colliders and implications for composite Higgs models with dark matter

Journal of High Energy Physics, 2018
Many composite Higgs models predict the existence of vector-like quarks with masses outside the reach of the LHC, e.g. m Q ≳ 2 TeV, in particular if these models contain a dark matter candidate.

Electroweak symmetry breaking and collider signatures in the next-to-minimal composite Higgs model

Journal of High Energy Physics, 2017
We conduct a detailed numerical analysis of the composite pseudo-Nambu-Goldstone Higgs model based on the next-to-minimal coset SO(6)/SO(5) ≅ SU(4)/Sp(4), featuring an additional SM singlet scalar in the spectrum, which we allow to mix with the Higgs ...

The LHC potential of vector-like quark doublets

Journal of High Energy Physics, 2018
The existence of new vector-like quarks is often predicted by models of new physics beyond the Standard Model, and the development of discovery strategies at colliders is the object of an intense effort from the high-energy community.
