Unification of Weak and Gravitational Interactions Stemming from Expansive Nondecelerative Universe Model

There is a deep interrelationship of the General Theory of Relativity and weak interactions in the model of Expansive Nondecelerative Universe. This fact allows an independent determination of the mass of vector bosons Z and W, as well as the time of separation of electromagnetic and weak interactions. In the early stage of the Universe creation, i.e. in the lepton era an equilibrium of protons and neutrons formation existed at the temperature about 10 10 K which corresponds to the energy of 1 MeV (a lower side of the range of weak interaction energies). The amount of neutrons was stabilized by processes including antineutrinos (eq.1) or neutrinos (eq.2) such as ν + p → n+ e (1) e− + p → n+ ν (2) The cross section σrelated to the above processes can be expressed [1, 2] as
