Gauge theories of gravity
… which can dynamically replicate the effects of dark radiation in the early Universe. In a simplified version of the theory, part of the torsion is removed via multipliers without detriment to the known phenomenology. This procedure introduces classical ghosts to the Minkowski background, but …
