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.

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.

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.
