Is a Coherent Picture of Massive Neutrinos Emerging?

Abstract

The hypothesis that neutrinos are massive has a strong experimental support; however, the information we have is quite limited, and many possibilities are open. Theoretical considerations might help fill the gaps (or foresee regularities), as we illustrate with a specific example.
