Seeking the Small Silent Type

One of the great breakthroughs in physics of the past decade has been the evidence for neutrino mass from neutrino oscillation experiments. However, incorporating these tiny masses into the Standard Model is not straightforward. Many extensions which include neutrino mass also introduce "sterile" neutrino partners. These neutrinos do not interact via the strong, electromagnetic OR weak interaction. But they may participate in neutrino oscillations. This talk considers the motivation and impact of sterile neutrino models. It then focuses on the MiniBooNE experiment, which is presently taking data and which may shed light on the question.
