abstract
CP phase determination for the near future long baseline experiments, T2HK and DUNE, will require precise measurements of the oscillation probabilities. However, the uncertainty in the Earth's density must be considered in determining these oscillation probabilities. Therefore, in this study, we update the individual sensitivities of these experiments for determining the current unknowns in the standard three flavor scenario considering the latest configuration and also the complementarity between them while considering the uncertainty in the density. Our study showed that this uncertainty has a non-negligible impact on the precision of the CP phase determination particularly for DUNE.

Effects of the Matter Potential at One-Loop Level on Neutrino Oscillations in Long-Baseline Experiments
Including the Standard Model one-loop correction to the matter potential, a 2.0% increase when expressed with G_mu, improves DUNE's mass-ordering sensitivity by about 0.4 sigma and reaches 5 sigma four to nine days earlier.
