A UV Complete Compositeness Scenario: LHC Constraints Meet The Lattice

Understand

We investigate a recently proposed UV-complete composite Higgs scenario in the light of the first LHC runs.

• The model is based on a $SU(4)$ gauge group with global flavour symmetry breaking $SU(5) \to SO(5)$, giving rise to pseudo Nambu-Goldstone bosons in addition to the Higgs doublet.
• This includes a real and a complex electroweak triplet with exotic electric charges.
• Including these, as well as constraints on other exotic states, we show that LHC measurements are not yet sensitive enough to significantly constrain the model's low energy constants.
