Mass Generation from Lie Algebra Extensions
arXiv:hep-th/0207095 · doi:10.1023/B:IJTP.0000006023.78109.19
Abstract
Applied to the electroweak interactions, the theory of Lie algebra extensions suggests a mechanism by which the boson masses are generated without resource to spontaneous symmetry breaking. It starts from a gauge theory without any additional scalar field. All the couplings predicted by the Weinberg-Salam theory are present, and a few others which are nevertheless consistent within the model.
