Gravitational matter-antimatter asymmetry and four-dimensional Yang-Mills gauge symmetry
Tóm tắt
A formulation of gravity based on the maximum fourdimensional Yang-Mills gauge symmetry is studied. The theory predicts that the gravitational force inside matter (fermions) is different from that inside antimatter. This difference could lead to the cosmic separation of matter and antimatter in the evolution of the Universe. Moreover, a new gravitational long-range spin-force between two fermions is predicted, in addition to the usual Newtonian force. The geometrical foundation of such a gravitational theory is the Riemann-Cartan geometry, in which there is a torsion. The results of the theory for weak fields are consistent with previous experiments.

Previous experiments such as the Michelson experiment, the moving-mass experiment, the experiment of lifetime dilation of unstable-particle decay in flight, etc. have been analyzed in this framework. The results are consistent with experiments because this new framework has the four-dimensional symmetry for physical laws.
