Conservation of the Dirac Current in Models with a General Spin Connection

الأصل · EN

Here I obtain the conditions necessary for the conservation of the Dirac current when one substitutes the assumption γᵃ|B=0 for γᵃ|B=[VB,γᵃ], where the γᵃs 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. D8, 2398 (1973)].
