Description
Lorentz gauge theory of gravity with a symmetry breaking "Cartan khronon" field demonstrates its successful explanation for the $\Lambda$CDM model, with an emergent integration 3-form behaving as ideal dust. Within the chiral scheme of this theory, only the right-handed regime recovers the general relativity. A natural question that arises is what happens with the left-handed gravity? When both right- and left- handed gravity are included, we find the integration 3-form is essential to formulate non-trivial cosmology. This talk discusses cosmology based on both-handed gauge theory of gravity and why the integration 3-form is a compelling dark matter candidate.
