For a narrow band of values of the top quark and Higgs boson masses , the Standard Model Higgs potential develops a false minimum at energies of about 10 ^ { 16 } GeV , where primordial Inflation could have started in a cold metastable state .
A graceful exit to a radiation-dominated era is provided , e.g . , by scalar-tensor gravity models .
We pointed out that if Inflation happened in this false minimum , the Higgs boson mass has to be in the range 126.0 \pm 3.5 GeV , where ATLAS and CMS subsequently reported excesses of events .
Here we show that for these values of the Higgs boson mass , the inflationary gravitational wave background has be discovered with a tensor-to-scalar ratio at hand of future experiments .
We suggest that combining cosmological observations with measurements of the top quark and Higgs boson masses represents a further test of the hypothesis that the Standard Model false minimum was the source of Inflation in the Universe .
