The best way to probe CP violation in the lepton sector is with long-baseline
accelerator neutrino experiments in the appearance mode. I will show that it is
possible to discover CP violation with disappearance experiments only, by
combining JUNO for electron neutrinos and DUNE or Hyper-Kamiokande for
muon neutrinos. While the maximum sensitivity to discover CP is quite modest,
some values of δ may be disfavored by > 3σ depending on the true value of δ.
Neutrino oscillation experiments will be entering the precision era in the next
decade. Correctly estimating the confidence intervals from data for the oscillation
parameters requires very large Monte Carlo data sets involving calculating the
oscillation probabilities in matter many, many times. In this talk, I will leverage
past work to present a new, fast, precise technique for calculating neutrino
oscillation probabilities in matter optimized for long-baseline neutrino oscillations
called NuFast. I will also present recent results for atmospheric and solar
neutrinos.
