摘要：
A supersymmetric model which naturally accommodates MeV tau neutrinos within the framework of gauge-mediated supersymmetry breaking is described. The lepton number violation is originally introduced in the messenger sector of the theory. A large slepton-Higgs mixing mass and a small lepton-higgsino mixing mass are generated at one loop. The scalar tau neutrino has a non-vanishing vacuum expectation value. This results in a non-zero nu(tau) mass which is in the range of 1-10 MeV. (C) 1999 Elsevier Science B.V.
