Abstract
I propose a unified model of particle physic and cosmology based on both a new extension of the standard particle model and the fundamental principle of the standard cosmology. Beyond the standard model, I introduce several species of dark fields with the dark symmetry of Z 2 ⊗ Z 2 ′ , the inflation field, cold dark matter (CDM) and dark energy (DE) are of course included among them. The model can coherently and completely describe the origin and evolution of the universe from the primordial inflation to the reheating, to the baryogenesis, to the current CDM and DE, and also the neutrino mass generation mechanism. For the energy evolution of each phase, I give its dynamical system of equations, and solve them by some special techniques. The numerical results can clearly show how each evolution is successfully implemented, furthermore, the model demonstrates that the DE genesis is purely from the CDM condensation, which is essentially a reverse process of the primordial slow-roll inflation, there is not the so-called "cosmological constant energy". By use of fewer input parameters, the model not only exactly reproduces the measured inflationary data and the current energy density budget, but also finely predicts such important values as the tensor-to-scalar ratio r 0. 0 5 ≈ 1. 6 8 × 1 0 − 6 , the inflaton mass M Φ ≈ 5. 0 5 × 1 0 1 0 GeV, the reheating temperature T r e ≈ 8. 2 9 × 1 0 1 0 GeV, the CDM mass M S ≈ 2 5 6 GeV, η B ≈ 6. 1 4 × 1 0 − 1 0 and h ≈ 0. 7 3 , in particular, the model smoothly clarifies and eliminates the "Hubble tension". In short, the unified model newly establishes the deeper and closer relations between particle physics and cosmology, therefore we expect the ongoing and future experiments to test the model.
