Detailed analysis of one-loop neutrino masses from the generic supersymmetric standard model

In the generic supersymmetric standard model which has no global symmetry enforced by hand, lepton number violation is a natural consequence. Supersymmetry, hence, can be considered the source of experimentally demanded properties for the neutrinos beyond the standard model. With an efficient formulation of the model, we perform a comprehensive detailed analysis of all (fermion-scalar) one-loop contributions to neutrino masses.
