Parity violation in Poincaré gauge gravity
arXiv:2010.16276 · doi:10.1142/S0219887821500225
Abstract
We analyse the parity violation issue in the Poincaré gauge theory of gravity for the two classes of models which are built as natural extensions of the Einstein-Cartan theory. The conservation laws of the matter currents are revisited and we clarify the derivation of the effective Einstein field equation and the structure of the effective energy-momentum current for arbitrary matter sources.
