The massive neutrino-like particle of the non-linear electromagnetic   field theory
  A special non-linear electromagnetic field theory - the curvilinear wave electrodynamics (CWED), whose equation in the matrix form is similar to the equation of the Dirac lepton theory, is offered. It is shown that the solution of this equation is the motion of the circilarly polarized electromagnetic wave on a circular trajectory. It is also shown that such wave can be considered as a massive neutral particle with half spin, similar to neutrino. This theory is mathematically concurrent to the neutrino theory of Standard Model, but does not have the contradictions of the Standard Model with last data of neutrino experiments.
