Spinor field in generalized Krein space quantization.
In previous papers it has been shown that the presence of negative-norm states or negative-frequency solutions is indispensable for a fully covariant quantization (Krein space quantization) of the minimally coupled free scalar field in de Sitter spacetime. The new method of quantization has been ext...

The new method of quantization has been extended to free boson fields (charged scalar field, massive and massless vector field) in Minkowski spacetime. In this paper, quantization of free spinor field is reformulated in generalized Krein space. The presence of unphysical negative-frequency states plays the role of an automatic renormalization tool for the theory. En artículos anteriores se ha demostrado que la presencia de estados de norma negativa o de soluciones de frecuencia negativa es indispensable para una cuantización totalmente covariante (cuantización del espacio de Krein) del campo libre escalar en el espacio-tiempo de de Sitter. El nuevo método de cuantización se ha extendido a los campos de bosones libres (campo escalar cargado, campos vectoriales masivos y sin masa) en el espacio-tiempo de Minkowski. En este artículo la cuantización del campo de spinores libres se reformula en el espacio generalizado de Krein. La presencia de estados de frecuencia negativa no físicos juega un papel en la herramienta automática de renormalización para la teoría. pubtype: Academic Journal doctype: Article src: R language: English refInfo: copyright: @attributes: flag: Y custom: Copyright of Revista Cubana de Física is the property of Universidad de La Habana and its content may not be copied or emailed to multiple sites without the copyright holder's express written permission.
