Dirac's scalar field as dark energy within the frameworks of conformal theory of gravitation in Weyl-Cartan space
arXiv:1006.4761
Abstract
Equations of the conformal theory of gravity with a Dirac scalar field in a Weyl-Cartan space-time have been derived. An exact solution of the equation for a scalar field, which has kind of a decreasing exponential function, has been found. This allows to explain a significant decrease (during of the period of inflation) the energy of physical vacuum (dark energy), which has been identified with the energy of the Dirac scalar field.
