Description
Neutrino physics is entering an era of precision measurement, offering unprecedented opportunities to probe neutrino properties. This talk will discuss three examples. First, we present a new approach to measuring the CP-violating phase in neutrino mixing. This involves an up-down flux ratio for sub-GeV atmospheric neutrinos. For the example of Hyper-Kamiokande --- the first experiment with sufficient atmospheric-neutrino statistics in this energy range --- this approach can surpass the sensitivity of accelerator long-baseline experiments near the maximally CP-violating values $\delta = \pi/2$ and $3\pi/2$. Second, we show that DUNE can make a precise measurement of the total flux of $^8$B solar neutrinos via neutral-current interactions with argon. Combined with charged-current measurements, this would enable the most precise measurements of the solar neutrino mixing parameters using neutrino from the Sun. Finally, we discuss the ability to probe light dark matter via its annihilation to neutrinos.
