A hidden symmetry of complex spacetime and the emergence of the standard model algebraic structure

Year: 2025

Type: article

Abstract: When spacetime is considered as a subspace of a wider complex spacetime manifold, there is a mismatch of the elementary linear representations of their symmetry groups, the real and complex Poincaré groups. In particular, no spinors are allowed for the complex case. When a spinh structure is implemented on principal bundles in complex spacetime, one is naturally led to an algebraic structure similar to the one of the standard model.
