Neutrinos: Recent Developments and Future Challenges
Coordinators: Graciela Gelmini, Danny Marfatia, Sandip Pakvasa
Two major advances in neutrino physics have occurred recently, one at the oscillation front, the other at the astrophysical front: the mixing angle θ13 has been found to not be too small, and IceCube has ushered in the era of neutrino astronomy via the detection of cosmic neutrinos. The implications of these developments for the future of neutrino physics and neutrino astronomy are profound. With five of the oscillation parameters now measured, only the Dirac CP phase and the nature of the mass hierarchy remain unknown. Measurements of these will help determine the structure of the neutrino mass matrix. The IceCube observation of cosmic neutrinos immediately raises the question of their origin, and may answer the age-old question of the origin of ultra high-energy cosmic rays.
Within this context, the theme of this conference is to evaluate the scientific merit of different options for a world-wide experimental neutrino program in the near future.
