Dark matter candidate from torsion
arXiv:2112.03957 · doi:10.1016/j.physletb.2022.137488
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.
