Confront a dilaton model with the LHC measurements

Abstract: We study the scalar potential and investigate a couple of scenarios for the symmetry breaking mechanisms with a dilaton model which is derived from the geometry. We examine the LHC constraints for the couplings of Higgs-weak vector bosons and Higgs self-couplings in this model, which identifies the parameter space where the discovered Higgs boson $m_h=125$ GeV can be dilaton dominant and the features of Higgs self-couplings are explored. It is found that via the measurement of Higgs pair production, the High Luminosity LHC running can either confirm or rule out the dilaton dominance.
