I start with the big questions in our field, broken down into four categories: horizontal, vertical, heaven, and hell. Then I discuss how we attack the big questions in each category during the next twenty years. I argue for a synergy between many different approaches taken in our field.

In this talk I review what we have learned and why neutrino mass is so important. Neutrino masses and mixings are already shedding new insight into the origin of flavor. Given the evidences for neutrino mass, leptogenesis is gaining momentum as the origin of cosmic baryon asymmetry. Best of all, we will learn a lot more in the coming years.

Even though this is a useful simplifying assumption, it is too restrictive to accommodate a large variety of phenomenological possibilities. It predicts that the lightest supersymmetric particle (LSP) is

The masses and couplings of the right-handed neutrino field are suppressed by supersymmetry breaking, in a way similar to the ...
