【 摘 要 】

The nature of the scalar field responsible for the cosmological inflation, the "inflaton", is found to be rooted in the most fundamental concept of the Weyl's differential geometry: the parallel displacement of vectors in curved space-time. Within this novel dynamical scenario, the standard electroweak theory of leptons based on the SU(2)L⊗ U(1)Yas well as on the conformal groups of spacetime Weyl's transformations is analyzed within the framework of a general-relativistic, co-covariant scalar-tensor theory that includes the electromagnetic and the Yang-Mills fields. A Higgs mechanism within a spontaneous symmetry breaking process is identified and this offers formal connections between some relevant properties of the elementary particles and the dark energy content of the Universe. An "Effective Cosmological Potential": Veffis expressed in terms of the dark energy potential: via the "mass reduction parameter": , a general property of the Universe. The mass of the Higgs boson, which is considered a "free parameter" by the standard electroweak theory, by our theory is found to be proportional to the geometrical mean: of the Planck mass, MPand of the mass which accounts for the measured Cosmological Constant, i.e. The measured content of vacuum-energy in the Universe. The experimental result obtained by the ATLAS and CMS Collaborations at CERN in the year 2012: MH= 125.09(GeV/c2) leads by our theory to a value: Meff∼ 3.19 • 10-6(eV/c2). The peculiar mathematical structure of Veffoffers a clue towards the resolution of a most intriguing puzzle of modern quantum field theory, the "Cosmological Constant Paradox".
