The non-singular Trautman-Kopczynski big-bang model and a torsional spinor description of dark matter

A view is taken up whereby the non-singular Trautman-Kopczynski big-bang creation of the Universe produced a highly torsional hot state at early stages of the cosmic evolution which particularly brought about the for-mation of a dark matter cloud. It is thus assumed that the combination of Einstein-Cartan's theory with the torsionful version of the two-component epsilon-formalism of Infeld and van der Waerden supplies a natural local description of dark mat -ter in terms of uncharged spin-one massive fields. In the case of either handedness, the pertinent spinor field equation arises directly from a suitable form of the world Bianchi identity. It appears that each such field equation bears a term that is thought of as carrying part of the information on the mass of the fields. The whole information turns out to be extracted by well prescribed derivatives of certain couplings involving the fields and spinor torsion pieces in such a way that the mass of dark matter is really thought of as arising from the interaction between the fields and spinor torsion.

The spinor field equation arises from the world Bianchi identity, and the information on the mass of the fields is extracted through prescribed derivatives of certain couplings involving the fields and spinor torsion.
