The Unhiggs

Understand

We examine a scenario where the Higgs is part of an approximate conformal field theory, and has a scaling dimension greater than one.

• Such an unparticle Higgs (or Unhiggs) can still break electroweak symmetry and unitarize WW scattering, but its gauge couplings are suppressed.
• An Unhiggs model has a reduced sensitivity of the weak scale to the cutoff, and can thus provide a solution to the little hierarchy problem.
