Common exotic decays of top partners
Nicolas Bizot, Giacomo Cacciapaglia, Thomas Flacke
Many standard model extensions that address the hierarchy problem contain Dirac-fermion partners of the top quark, which are typically expected around the TeV scale. Searches for t…
Classification of NLO operators for composite Higgs models
T. Alanne, N. Bizot, G. Cacciapaglia +1
We provide a general classification of template operators, up to next-to-leading order, that appear in chiral perturbation theories based on the two flavour patterns of spontaneous…
Non-perturbative analysis of the spectrum of meson resonances in an ultraviolet-complete composite-Higgs model
Nicolas Bizot, Michele Frigerio, Marc Knecht +1
We consider a vector-like gauge theory of fermions that confines at the multi-TeV scale, and that realizes the Higgs particle as a composite Goldstone boson. The weak interactions…
Fermionic extensions of the Standard Model in light of the Higgs couplings
Nicolas Bizot, Michele Frigerio
As the Higgs boson properties settle, the constraints on the Standard Model extensions tighten. We consider all possible new fermions that can couple to the Higgs, inspecting sets…
