Combined Constraints on Holographic Bosonic Technicolor

Understand

We consider a model of strong electroweak symmetry breaking in which the expectation value of an additional, possibly composite, scalar field is responsible for the generation of fermion masses.

• The dynamics of the strongly coupled sector is defined and studied via its holographic dual, and does not correspond to a simple, scaled-up version of QCD.
• We consider the bounds from perturbative unitarity, the S parameter, and the mass of the Higgs-like scalar.
• We show that the combination of these constraints leaves a relatively limited region of parameter space viable, and suggests the qualitative features of the model that might be probed at the LHC.
