We propose a gauge theory of gravity with heavy gravitons. In this framework, we examine whether renormalization effects can cause Newton's constant to change dramatically with energy, perhaps even reducing the scale of quantum gravity to the TeV region. For the Standard Model (SM) Higgs boson, with mass 125GeV, we derive the invisible width of Higgs boson decay into heavy gravitons and calculate the ratios of partial widths and couplings for the Higgs decays into heavy gravitons and W vector bosons. This proposition may reveal Higgs and graviton properties for new physics Beyond Standard Model (BSM).
