TL;DR: In this article, it is argued that such rescalings naturally lead to the presence of torsion in the space-time derivative of a spinor, and it is further shown that, in standard general relativity, a circularly polarized gravitational wave produces a rotation effect along rays intersecting it similar to, and apparently consistent with, the local torsions of the Einstein-Cartan-Sciama-Kibble theory.
Abstract: Conformal rescalings of spinors are considered, in which the factor Ω, ine

a. It is further shown that, in standard general relativity, a circularly polarized gravitational wave produces a (nonlocal) rotation effect along rays intersecting it similar to, and apparently consistent with, the local torsion of the Einstein-Cartan-Sciama-Kibble theory. The results of these deliberations are suggestive rather than conclusive.
