Electroweak gauge fields, particles, and antiparticles arise from   probability
  Probabilities of events are expressed by the spinor functions and by operators of a probability creation and by operators of a probability annihilation. The motion equations in form of the Dirac equations with the additional fields are obtained for these spinor functions. Some of these additional fields behave as the gauge fields and others behave as the mass members. Such motion equations, contained all five elements of Clifford's pentad, is invariant for the electroweak gauge transformations. The creation operators and the annihilation operators of particles and antiparticles obtained from these probabilistic functions. The motion equation of the U(2) Yang-Mills field components is formulated similarly to the Klein-Gordon equation with the nonzero mass.
