摘要：

In this paper, we combine the nu-two-Higgs-doublet-model with the inverse seesaw mechanisms. In this model, the Yukawa couplings involving the sterile neutrinos and the exotic Higgs bosons can be of order 1 in the case of a large tan beta. We calculated the corrections to the Z-resonance parameters R-li, A(li), and N-nu, together with the l(1) -> l(2)gamma branching ratios and the muon anomalous g - 2. Compared with the current bounds and plans for the future colliders, we find that the corrections to the electroweak parameters can be constrained or discovered in much of the parameter space.
