Gravitational four-fermion interaction on the Planck scale
arXiv:1201.4226 · doi:10.1016/j.physletb.2012.01.072
Abstract
The four-fermion gravitational interaction is induced by torsion, and gets essential on the Planck scale. On this scale, the axial-axial contribution dominates strongly in the discussed interaction. The energy-momentum tensor, generated by this contribution, is analyzed, as well as stability of the problem with respect to compression. The trace of this energy-momentum tensor can be negative.
