Constructing a composite Higgs model with built-in large separation of scales

Understand

Experimentally the existence of a light 125 GeV Higgs boson is well established but so far no other heavier resonances have been observed.

• Viable models to describe the Higgs boson as composite particle require hence to exhibit a large separation of scales.
• This occurs naturally in systems located near a conformal fixed point irrespective whether the system lies outside or inside the conformal window.
• We demonstrate the latter case by investigating a mass-split model with four light and six heavy flavors.
