Description
In this talk, I present a bottom-up holographic model dual to a strongly coupled field theory which incorporates the spontaneous breaking of an approximate global symmetry yielding the SO(5)/SO(4) coset important for minimal composite-Higgs models. The gravity solution is smooth, mimicking confinement on the field theory side. A set of boundary terms are added to the gravity, introducing additional symmetry-breaking effects, that capture the results of coupling the dual field theory to a weakly coupled sector. This results in breaking the SO(4) to an SO(3) subgroup via vacuum misalignment as a toy model for the electroweak symmetry breaking. We compute the spectrum of fluctuations of the model, focusing on the Higgs-like excitations and comparing their mass to heavier modes.
