Holographic Technidilaton and LHC searches

Understand

We analyze in detail the phenomenology of a model of dynamical electroweak symmetry breaking inspired by walking technicolor, by using the techniques of the bottom-up approach to holography.

• The model admits a light composite scalar state, the dilaton, in the spectrum.
• We focus on regions of parameter space for which the mass of such dilaton is 125 GeV, and for which the bounds on the precision electroweak parameter S are satisfied.
• This requires that the next-to-lightest composite state is the techni-rho meson, with a mass larger than 2.3 TeV.
