DUNE: How I learned to stop worrying and love the neutrino
Since the discovery of neutrino oscillations more than twenty years ago, we have made steady progress on understanding neutrino properties with ever more challenging experiments. Today, we know that the fundamental parameters that govern this process take on some peculiar values and that they set the stage for CP violation, namely an imbalance between neutrinos and antineutrinos in the oscillation process. We hope one day to understand the origin of these parameters, and if neutrinos do indeed exhibit CP violation, whether it is related to why the universe is matter dominated. The Deep Underground Neutrino Experiment (DUNE), now under construction, is one of the most ambitious particle physics projects to be carried out in the US, and seeks to make decisive measurements and discoveries on the properties of the neutrino. In this colloquium, I will focus on some of the unique challenges we face at DUNE, with some focus on those being confronted at SLAC.
Hirohisa Tanaka grew up on Long Island, New York and earned his AB from Harvard University and PhD from Stanford University, studying radiative decays in SLAC’s Group C on BaBar. As postdoc at Princeton, he worked on the MiniBooNE neutrino oscillation experiment, after which he worked on the T2K long baseline neutrino oscillation experiment at UBC and the University of Toronto. He came back to SLAC in 2018 to join the accelerator-based neutrino effort.
