%0 Journal Article %T A See-Saw Mechanism for Large Neutrino Mixing from Small Quark and Lepton Mixings %A Isabella Masina %J Physics %D 2000 %I arXiv %X I introduce and sketch the main features of those see-saw models where a large atmospheric mixing can be achieved starting from nearly diagonal matrices for charged leptons, Dirac neutrinos and Majorana right-handed neutrinos. It turns out that these models can be realized in Grand Unified Theories and they are well compatible with the related phenomenology of fermion masses and mixings. %U http://arxiv.org/abs/hep-ph/0005239v1
