Dirac spinor fields in the teleparallel gravity: comment on "Metric-affine approach to teleparallel gravity"
Maluf, J. W.
Original · EN
We show that the coupling of a Dirac spinor field with the gravitational field in the teleparallel equivalent of general relativity is consistent. For an arbitrary SO(3,1) connection there are two possibilities for the coupling of the spinor field with the gravitational field. The problems of consistency raised by Y. N. Obukhov and J. G. Pereira in the paper Metric-affine approach to teleparallel gravity [gr-qc/0212080] take place only in the framework of one particular coupling. By adopting an alternative coupling the consistency problem disappears.
