The non-singular Trautman-Kopczy\'nski big-bang model and a torsional spinor description of dark matter

摘要
A view is taken up whereby the non-singular Trautman-Kopczy\'nski big-bangcreation of the Universe produced a highly torsional hot state at early stagesof the cosmic evolution which particularly brought about the formation of adark matter cloud. It is thus assumed that the combination of Einstein-Cartan'stheory with the torsionful version of the two-component {\epsilon}-formalism ofInfeld and van der Waerden supplies a natural local description of dark matterin terms of uncharged spin-one massive fields. In the case of eitherhandedness, the pertinent spinor field equation arises directly from a suitableform of the world Bianchi identity. It appears that each such field equationbears a term that is thought of as carrying part of the information on the massof the fields. The whole information turns out to be extracted by wellprescribed derivatives of certain couplings involving the fields and spinortorsion pieces in such a way that the mass of dark matter is really thought ofas arising from the interaction between the fields and spinor torsion.
