Kaluza-Klein Theory without Extra Dimensions: Curved Clifford Space
arXiv:hep-th/0412255 · doi:10.1016/j.physletb.2005.03.052
Abstract
A theory in which 16-dimensional curved Clifford space (C-space) provides a realization of Kaluza-Klein theory is investigated. No extra dimensions of spacetime are needed: "extra dimensions" are in C-space. It is shown that the covariant Dirac equation in C-space contains Yang-Mills fields of the U(1)xSU(2)xSU(3) group as parts of the generalized spin connection of the C-space.
