Description

The best way to probe CP violation in the lepton sector is with long-baseline accelerator neutrino experiments in the appearance mode: the appearance of ${\nu }_e$ in predominantly ${\nu }_{\mu }$ beams. Here we 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 (1.6$\sigma$ with 6 years of JUNO and 13 years of DUNE), some values of $\delta$ may be disfavored by >3$\sigma$ depending on the true value of $\delta$.
