Hadron dilation, shear and spin as components of the intrinsic hypermomentum current and metric-affine theory of gravitation

The infinite unitary irreducible spinor representations of the SL(3,R) algebra of hadron excitations are embedded in a global GA(4,R) with intrinsic dilation, shear and spin pieces in its hypermomentum current (i.e. the affine generalization of angular momentum). When gauged over a spacetime with a local Minkowski metric, GA(4,R) reproduces the metric-affine theory of gravity, in which the hypermomentum is coupled to the connection and the energy-momentum to the tetrad.
