Geometric Spinors, Generalized Dirac Equation and Mirror Particles

Abstract

It is shown that since the geometric spinors are elements of Clifford algebras, they must have the same transformation properties as any other Clifford number. In general, a Clifford number $\Phi$ transforms into a new Clifford number ${\Phi }^{\prime }$ according to $\Phi \to {\Phi }^{\prime }=\mathrm{R}\Phi \mathrm{S}$, i.e., by the multiplication from the left and from the right by two Clifford numbers $\mathrm{R}$ and $\mathrm{S}$. We study the case of $Cl(1,3)$, which is the Clifford algebra of the Minkowski spacetime. Depending on choice of $\mathrm{R}$ and $\mathrm{S}$, there are various possibilities, including the transformations of vectors into 3-vectors, and the transformations of the spinors of one minimal left ideal of $Cl(1,3)$ into another minimal left ideal. This, among others, has implications for understanding the observed non-conservation of parity.
