Dark matter candidate from torsion
Álvaro de la Cruz Dombriz, Francisco José Maldonado Torralba, David F. Mota
Abstract
The stable pseudo-scalar degree of freedom of the quadratic Poincaré Gauge theory of gravity is shown to be a suitable dark matter candidate. We find the parameter space of the theory which can account for all the predicted cold dark matter, and constrain such parameters with astrophysical observations.
