Remark on Immirzi Parameter, Torsion, and Discrete Symmetries

High Energy Physics - Theory 2009-11-11 v2

Abstract

We point out that the new interaction of spinning particles with the torsion tensor, discussed recently, is odd under charge conjugation and time reversal. This explains rather unexpected symmetry properties of the induced effective 4-fermion interaction.
