Fakultät für Physik Physikalisches Kolloquium Prof. Dr. Dietrich Bödeker Universität Bielefeld The Nobel Prize in Physics 2015: The discovery of neutrino oscillations, which shows that neutrinos have mass The 2015 Physics Nobel Prize was awarded to Takaaki Kajita and Arthur B. McDonald. They were the leading scientists in two experiments, SuperKamiokande and Sudbury Neutrino Observatory (SNO), which demonstrated that neutrinos can change their type, the so-called flavor, while they travel through space. This phenomenon is interpreted as ‘neutrino oscillations’, which requires that neutrinos have a non-zero mass. This is the first discovery of physics beyond the Standard Model of Particle Physics, which assumed neutrinos to be massless. I introduce the physics of neutrinos and the experiments which led to this breakthrough. Then I discuss its theoretical interpretation and possible consequences for particle physics and cosmology.
