内容記述 | The radiatively induced neutrino mass matrix is investigated on the basis of an SU(5) SUSY model. In order to evade the proton decay, an ansatz based on a discrete symmetry Z_2 is assumed: although, at the unification scale, we have two types of superfields Ψ_<L(±)>) = 5^^-_L(±)+10_L(±), which are transformed as Ψ_<L(±)>→Ψ±_<L(±)> under the discrete symmetry Z2, the particles Ψ_<L(+)> are decouple after the SU(5) symmetry is broken, so that our quarks and leptons belong to Ψ_<L(-)>. The R-parityviolating terms for our quarks and leptons Ψ_<L(-)> are basically forbidden under the symmetry Z_2. However, we assume that mixings between members of Ψ_<L(+)> and those of Ψ_<L(-)> are in part caused after SU(5) is broken. As a result, the R-parity-violating interactions are in part allowed, so that the neutrino masses are radiatively generated, while the proton decay due to the R-parity violating terms is still forbidden because the term d^c_Rd^c_RucR has z = -1. | |||||
