Query: The motion equation for massive fermions and bosons without Higgs   The motion equation with nonzero mass, invariant for weak isospin
transformation, can be obtained from the Dirac equation by the adding of the
Clifford pentad fifth element. The motion equation of the SU(2) Yang-Mills
field components is similar to the Klein-Gordon equation with the nonzero mass.
