6. One may worry that such a particle theory, in which particles always have actual positions but have no additional actual discrete degrees of freedom corresponding, for example, to spin, cannot do justice to QFT, for which spin and other discrete degrees of freedom are often regarded as playing a crucial role. However, additional actual discrete degrees of freedom are entirely unnecessary: as Bell has shown in [6], the straightforward extension of Bohmian mechanics to spinor-valued wave functions, which we use here, accounts for all phenomena involving spin

15. The choice of Q for a given QFT, such as QED, is, however, not unique. For instance, it is possible to devise a version of the theory in which the configuration variable Q represents only the configuration of the fermions [7]. We have argued in [8] that it is more natural to include photons among the particles, represented in Q.
