摘要：

We study the effect of the Higgs-exchange diagram for the lepton flavor violating muon-electron conversion process in nuclei in the supersymmetric see-saw model. The contribution is significant for a large value of tan P and a small value of a neutral heavy Higgs boson mass, in which case the ratio of the branching ratios of B(muN --> eN)/B(mu --> egamma) is enhanced. We also show that the target atom dependence of the conversion branching ratio provides information on the size of the Higgs exchange diagram. (C) 2003 Elsevier B.V. All rights reserved.
