Spin 1/2 Field Theory in the de Sitter space-time
arXiv:gr-qc/0005077
Abstract
A covariant quantization of the free spinor fields (s=1/2) in 4-dimensional de Sitter (dS) space-time based on analyticity in the complexified pseudo-Riemanian manifold is presented. We define the Wigthman two-point function , which satisfies the conditions of: a) positivity, b) locality, c) covariance, and d) normal analyticity. Then the Hilbert space structure and the field operators are defined. A coordinate-independent formula for the unsmeared field operator is also given.
