Phys. Rev. D 30, 2579–2584 (1984)Stochastic mechanics of spin-½ particlesReceived 3 July 1984; published in the issue dated 15 December 1984 Following the strategy of stochastic quantization, based on variational principles for processes taking values on a discrete configuration space, we give a detailed and self-contained description of the stochastic processes associated to a two-level quantum system, of interest for the physical description of spin-½ particles and Fermi fields. In particular we investigate the class of processes related to unperturbated quantum evolution and those simulating quantum-measurement procedures leading to mixture formation. © 1984 The American Physical Society URL:
