Abstract

It's been a remarkable decade in neutrino physics. Ten years ago this summer, at the 1998 neutrino conference in Takayama, the Super-Kamiokande collaboration reported the observation of neutrinos changing flavor, thereby establishing the existence of neutrino mass. A few years later, the SNO experiment solved the long-standing solar neutrino problem demonstrating that it too was due to neutrino oscillation. Just a few years after that, these effects were confirmed and the oscillation parameters were measured with man-made neutrino sources. Now, just in this last year, the same neutrinos which were the source of the 30 year old solar neutrino problem were measured for the first time in a real-time experiment. In this talk, I will explain how a set of experiments, especially ones in the last few years, have established a consistent framework of neutrino physics and also explain some outstanding questions. Finally, I will cover how a set of upcoming experiments hope to address these questions in the coming decade.
