Abstract

We show that the coupling of a Dirac spinor field \ensuremathψ with the gravitational field in the teleparallel equivalent of general relativity is consistent. For an arbitrary SO(3,1) connection \ensuremathω_\ensuremathμab there are two possibilities for the coupling of \ensuremathψ with the gravitational field. The problems of consistency raised by Y. N. Obukhov and J. G. Pereira, Phys. Rev. D 67, 044016 (2003), occur only in the framework of one particular coupling. By adopting an alternative coupling the consistency problem disappears.
