Real and complex fundamental partial compositeness [PDF]

open access: yesJournal 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

Supersymmetry versus Compositeness: 2HDMs tell the story

open access: yesPhysics Letters B, 2018
Supersymmetry and Compositeness are two prevalent paradigms providing both a solution to the hierarchy problem and a motivation for a light Higgs boson state. As the latter has now been found, its dynamics can hold the key to disentangle the two theories.

Weinberg’s Compositeness [PDF]

open access: yesSymmetry, 2022
Nearly 60 years ago, Weinberg suggested a criterion for particle “compositeness”, which has acquired a new life with the discovery of new, exotic hadrons. His idea resonates with model-based intuition. I discuss the role it plays in the context of another of Weinberg’s creations, the model-independent framework of effective field theories.

ATLAS search for new phenomena in dijet mass and angular distributions using pp collisions at s√=7 TeV [PDF]

open access: yes, 2013
Mass and angular distributions of dijets produced in LHC proton-proton collisions at a centre-of-mass energy s√=7 TeV have been studied with the ATLAS detector using the full 2011 data set with an integrated luminosity of 4.8 fb−1. Dijet masses up to ~ 4.

Multi-representation dynamics of SU(4) composite Higgs models: chiral limit and spectral reconstructions

open access: yesEuropean Physical Journal C: Particles and Fields, 2023
We present a lattice study of the SU(4) gauge theory with two Dirac fermions in the fundamental and two in the two-index antisymmetric representation, a model close to a theory of partial compositeness proposed by G. Ferretti.

Testing the mechanism of lepton compositeness

open access: yesSciPost Physics, 2021
Strict gauge invariance requires that physical left-handed leptons are actually bound states of the elementary left-handed lepton doublet and the Higgs field within the standard model. That they nonetheless behave almost like pure elementary particles

Loop-generated neutrino masses in composite Higgs models

open access: yesJournal of High Energy Physics, 2021
We present a composite scotogenic model for neutrino masses, which are generated via loops of ℤ2-odd composite scalars. We consider three different approaches to the couplings of the neutrinos (including three right-handed singlets) and the composite ...
