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.
