Conservation of the Dirac Current in Models with a General Spin Connection
arXiv:1210.0759
Abstract
Here I obtain the conditions necessary for the conservation of the Dirac current when one substitutes the assumption for , where the s are the Dirac matrices and "" represents the components of the covariant derivative. As an application, I apply these conditions to the model used in Ref. [M. Novello, Phys. Rev. {\bf D8}, 2398 (1973)].
