Composite dark matter and Higgs

Journal of High Energy Physics, 2017
We investigate the possibility that Dark Matter arises as a composite state of a fundamental confining dynamics, together with the Higgs boson. We focus on the minimal SU(4)×SU(4)/SU(4) model which has both a Dark Matter and a Higgs candidates arising as

Partially composite Higgs models: phenomenology and RG analysis

Journal of High Energy Physics, 2018
We study the phenomenology of partially composite-Higgs models where electroweak symmetry breaking is dynamically induced, and the Higgs is a mixture of a composite and an elementary state.

Gegenbauer Goldstones

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 ...

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
