Planck Scale Physics, GraviWeak Unification and the Higgs Inflation
Abstract
Starting with a theory of the discrete spacetime at the Planck scale, we developed a GraviWeak Unification (GWU)  a $Spin(4,4)$invariant model unified gravity with weak $SU(2)$ gauge and Higgs fields in the visible and invisible sectors of the Universe. Considering the GraviWeak symmetry breaking, we showed that the obtained subalgebras contain the selfdual lefthanded gravity in the OW, and the antiselfdual righthanded gravity in the MW. Finally, at the low energy limit, we have only the Standard Model (SM) and the EinsteinHilbert's gravity. The FroggattNielsen's prediction of the topquark and Higgs masses was given in the assumption that there exist two degenerate vacua in the SM. This prediction was improved by the next order calculations. We have developed a model of the Higgs Inflation using the GWU action. According to this inflationary model, a scalar field (inflaton) starts trapped from the "false vacuum" of the Universe at the Higgs field's VEV $v_2 \sim 10^{18}$ GeV. The interaction between the ordinary and mirror Higgs fields $\phi$ and $\widetilde{\phi}$ generates a Hybrid model by A.~Linde of the Higgs Inflation in our Universe.
