  • Abstract A spinning particle is described in terms of its position φ μ ( τ ) and of an additional spin degree of freedom ψ μ ( τ ) which is an odd element of a Grassmann algebra. Its motion is described by an action which is invariant under both general reparametrizations and local supergauge transformations. For a particular realization of the canonical commutation relations we obtain a first quantized version of the Dirac equation in an analogous fashion to the way that the Klein-Gordon… CONTINUE READING
