Handbook of vectorlike quarks: Mixing and single production

JA Aguilar-Saavedra, R Benbrik, S Heinemeyer… - Physical Review D …, 2013 - APS
We obtain constraints on the mixing of vectorlike quarks coupling predominantly to the third
generation. We consider all (seven) relevant types of vectorlike quarks, individually. The …

A first top partner hunter's guide

A De Simone, O Matsedonskyi, R Rattazzi… - Journal of High Energy …, 2013 - Springer
A bstract We provide a systematic effective lagrangian description of the phenomenology of
the lightest top-partners in composite Higgs models. Our construction is based on symmetry …

[HTML][HTML] Scenarii for interpretations of the LHC diphoton excess: two Higgs doublets and vector-like quarks and leptons

A Angelescu, A Djouadi, G Moreau - Physics Letters B, 2016 - Elsevier
An evidence for a diphoton resonance at a mass of 750 GeV has been observed in the data
collected at the LHC run at a center of mass energy of 13 TeV. We explore several …

Higgs low-energy theorem (and its corrections) in composite models

M Gillioz, R Gröber, C Grojean, M Mühlleitner… - Journal of High Energy …, 2012 - Springer
A bstract The Higgs low-energy theorem gives a simple and elegant way to estimate the
couplings of the Higgs boson to massless gluons and photons induced by loops of heavy …

Survey of vector-like fermion extensions of the Standard Model and their phenomenological implications

SAR Ellis, RM Godbole, S Gopalakrishna… - Journal of High Energy …, 2014 - Springer
A bstract With the renewed interest in vector-like fermion extensions of the Standard Model,
we present here a study of multiple vector-like theories and their phenomenological …

Probing top-partners in Higgs+ jets

A Banfi, A Martin, V Sanz - Journal of High Energy Physics, 2014 - Springer
A bstract Fermionic top-partners arise in models such as Composite Higgs and Little Higgs.
They modify Higgs properties, in particular how the Higgs couples to top quarks. Alas, there …

Unravelling an extended quark sector through multiple Higgs production?

S Dawson, E Furlan, I Lewis - Physical Review D—Particles, Fields, Gravitation …, 2013 - APS
In many new physics scenarios, the particle content of the Standard Model is extended and
the Higgs couplings are modified, sometimes without affecting single Higgs production. We …
