Models of neutrino masses and mixings
Guido Altarelli
We briefly review models of neutrino masses and mixings. In view of the existing experimental ambiguities many possibilities are still open. After an overview of the main alternati…

Grand Unification in Extra Dimensions and Proton Decay
Ferruccio Feruglio
We discuss baryon and lepton violation in the context of a simple 5-dimensional grand unified model, based on the orbifold S^1/(Z_2 x Z_2'). While gauge and Higgs degrees of freedo…

Large Neutrino Mixing in Grand Unified Theories
Ferruccio Feruglio
A non-minimal, semi-realistic version of supersymmetric SU(5) grand unified theory is discussed. The solution of the doublet-triplet splitting problem leads to a better agreement b…
