Pseudoscalar action in a Cartan spacetime

Journal Article · · Phys. Rev., D; (United States)

The Einstein-Cartan theory of gravitation is generalized by the addition of the most general action which is bilinear in the antisymmetric part of the connection and linear in the Levi-CIvita density and hence contains both scalar and pseudoscalar contributions. For arbitrary-spin fields new tensor and pseudotensor interactions arise while for spin-1/2 fields the theory reduces to Cartan's equations, apart from a reduction in the spin-spin coupling constant.
