Underlying models with a composite Higgs and their many collider signatures


Composite Higgs models attempt to address the hierarchy problem and to provide a dynamical explanation for electroweak symmetry breaking. In the first part of this talk, we survey a class of underlying models with a confining BSM gauge group and BSM fermions which are the constituents of a composite Higgs multiplet, as well as of BSM baryons (vector-like quarks) which are relevant to generate a mass term for the standard model quarks. Beyond the Higgs, the models predict further scalar resonances below the TeV scale as well as vector-like quarks at the TeV or multi-TeV scale. In the second part of the talk, we discuss the collider phenomenology of the light composite scalars, vector-like quarks, and their interplay. We determine constraints from current LHC searches and outline opportunities for searches at the LHC and future colliders.
