Dilaton at the LHC

Barger, Vernon, Ishida, Muneyuki, Keung, Wai-Yee

Understand

The dilaton, a pseudo-Nambu-Goldstone boson appearing in spontaneous scale symmetry breaking at a TeV scale f, may be found in Higgs boson searches.

  • The dilaton couples to standard model fermions and weak bosons with the same structure as the Higgs boson except for the overall strength.
  • Additionally, the dilaton couples to a Higgs boson pair.
  • The couplings of the dilaton to a gluon pair and a photon pair, appearing at loop level, are largely enhanced compared to the corresponding Higgs couplings.
