Abstract:
Based on the observables \MW, , \bar\sw~2(\MZ~2), we evaluate the parameters and at one-loop level within an electroweak massive vector-boson theory, which does not employ the Higgs mechanism. The theoretical results are consistent with the experimental ones on , , . The theoretical prediction for coincides with the standard-model one (apart from numerically irrelevant terms which vanish for \MH\to\infty). Non-renormalizability only affects and , which differ from the standard-model results by the replacement \log\MH\to\log\Lambda for a heavy Higgs mass, \MH (where denotes an effective UV cut-off).- electroweak interaction: model
