Inflation from the finite scale gauged Nambu–Jona-Lasinio model

open access: yesNuclear Physics B, 2017
The possibility to construct an inflationary universe scenario for the finite-scale gauged Nambu–Jona-Lasinio model is investigated. This model can be described by the Higgs–Yukawa type interaction model with the corresponding compositeness scale ...

A composite Higgs with a heavy composite axion [PDF]

open access: yesJournal of High Energy Physics, 2020
Abstract We consider the strong dynamics associated with a composite Higgs model that simultaneously produces dynamical axions and solves the strong CP problem. The strong dynamics arises from a new Sp or SU(4) hypercolor gauge group containing QCD colored hyperfermions that confines at a high scale.

Four-Fermion Limit of Gauge-Yukawa Theories [PDF]

open access: yes, 2015
We elucidate and extend the conditions that map gauge-Yukawa theories at low energies into time-honoured gauged four-fermion interactions at high energies.

On Composition of Torsors

open access: yesInternational Mathematics Research Notices, 2023
AbstractLet $K$ be a field, let $X$ be a connected smooth $K$-scheme, and let $G,H$ be two smooth connected $K$-group schemes. Given $Y \to X$ a $G$-torsor and $Z \to Y$ an $H$-torsor, we study whether one can find an extension $E$ of $G$ by $H$ so that the composite $Z \to X$ is an $E$-torsor.

Search for excited leptons in ℓℓγ final states in proton-proton collisions at s = 13 $$ \sqrt{\mathrm{s}}=13 $$ TeV

open access: yesJournal of High Energy Physics, 2019
A search is presented for excited electrons and muons in ℓℓγ final states at the LHC. The search is based on a data sample corresponding to an integrated luminosity of 35.9 fb−1 of proton-proton collisions at a center-of-mass energy of 13 TeV, collected ...

Probing Compositeness with Higgs Boson Decays at the LHC [PDF]

open access: yes, 2014
A method is proposed to directly probe the Higgs boson compositeness using the unique characteristics of a boosted Higgs boson produced in association with a weak gauge boson ($W^{\pm},Z$).

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.

Neutrino masses from low scale partial compositeness

open access: yesJournal 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.

g μ − 2 from Vector-like leptons in warped space

open access: yesJournal of High Energy Physics, 2017
The experimental value of the anomalous magnetic moment of the muon, as well as the LHCb anomalies, point towards new physics coupled non-universally to muons and electrons.
