Anomalous magnetic and quadrupole moments of theWboson in the two-Higgs-doublet model

Abstract
We present limits on the anomalous magnetic and quadrupole moments of the W boson in SU(2)U(1) models with two Higgs doublets. We give the contributions to these moments from the charged and neutral Higgs bosons beyond the standard model. The main result is that these extra components increase the moments by 0.1% and 0.03%, respectively.
