Query: High spin particles with spin-mass coupling   The classical and quantum model of high spin particles is proposed and
analyzed in this paper. The covariant quantization leads to the spectrum of the
particles with the masses correlated with their spins. The particles (and
anti-particles) appear to be orphaned as their potential anti-particle partners
are of different mass.
