Fermion Helicity Flip Induced by Torsion Field
arXiv:astro-ph/9904199 · doi:10.1209/epl/i1999-00323-8
Abstract
We show that in theories of gravitation with torsion the helicity of fermion particles is not conserved and we calculate the probability of spin flip, which is related to the anti-symmetric part of affine connection. Some cosmological consequences are discussed.
