Higher Spin Particles with Bosonic Counterpart of Supersymmetry
  We propose the relativistic point particle models invariant under the bosonic counterpart of SUSY. The particles move along the world lines in four dimensional Minkowski space extended by $N$ commuting Weyl spinors. The models provide after first quantization the non--Grassmann counterpart of chiral superfields, satisfying Klein--Gordon equation. Free higher spin fields obtained by expansions of such chiral superfields satisfy the N=2 Bargman--Wigner equations in massive case and Fierz--Pauli equations in massless case.
