Standard Model False Vacuum Inflation: Correlating the Tensor-to-Scalar Ratio to the Top Quark and Higgs Boson masses Masina, Isabella Notari, Alessio Quarks Bosons de Higgs Quarks Higgs bosons 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 ± 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 represent a further test of the hypothesis that the standard model false minimum was the source of inflation in the universe. 2019-05-10T12:49:43Z 2019-05-10T12:49:43Z 2012-05-09 2019-05-10T12:49:43Z info:eu-repo/semantics/article info:eu-repo/semantics/publishedVersion 0031-9007 https://hdl.handle.net/2445/132977 646983 eng Reproducció del document publicat a: https://doi.org/10.1103/PhysRevLett.108.191302 Physical Review Letters, 2012, vol. 108, num. 19, p. 191302 https://doi.org/10.1103/PhysRevLett.108.191302 (c) American Physical Society, 2012 info:eu-repo/semantics/openAccess 4 p. application/pdf American Physical Society Articles publicats en revistes (Física Quàntica i Astrofísica)
