Pseudoclassical description of a relativistic spinning particle

Spin and statistics in classical mechanics

“…S µν , of course, is the classical intrinsic spin tensor of the particle. This result may be obtained with aid of the classical Pauli-Lubanski vector 74 or directly from even 67 and odd 58 irreducible canonical realizations. From eqn (47), the intrinsic spin vector of a particle in its rest frame is obtained as…”
