摘要
The static electromagnetic properties of the W boson, Deltakappa and DeltaQ, are calculated in the SUL(3)xU(X)(1) model with right-handed neutrinos. The new contributions from this model arise from the gauge and scalar sectors. In the gauge sector there is a new contribution from a complex neutral gauge boson Y-0 and a singly charged gauge boson Y+/-. The mass of these gauge bosons, called bileptons, is expected to be in the range of a few hundred GeV according to the current bounds from experimental data. If the bilepton masses are of the order of 200 GeV, the size of their contribution is similar to that obtained in other weakly coupled theories. However, the contributions to both DeltaQ and Deltakappa are negligible for very heavy or degenerate bileptons. As for the scalar sector, a scenario is examined in which the contribution to the W form factors is identical to that of a two-Higgs-doublet model. It is found that this sector would not give large corrections to Deltakappa and DeltaQ.
