Abstract
We point out the possibility that reactor measurement of theta_13, when combined with high-statistics nu_e appearance accelerator experiments, can detect leptonic CP violation. Our proposal is based on a careful statistical analysis under reasonable assumptions on systematic errors, assuming 2 years running of the neutrino mode J-PARC -> Hyper-Kamiokande experiment and a few years running of a reactor experiment with 100 ton detectors at the Kashiwazaki-Kariwa nuclear power plant. We show that the method can be arranged to be insensitive to the intrinsic parameter degeneracy but is affected by the one due to unknown sign of Delta m^2_31.
The paper's own sentences, arranged. Each label is drawn from a closed vocabulary; the number beside it is the probability the classifier gave that label. No sentence in this record was written by a model.

It should be noticed, as observed and emphasized in [ref] , that the CP sensitivity is severely damaged by the parameter degeneracy due to unknown neutrino mass hierarchies [ref] .

For a precisely measured $$, there can be three different parameter degeneracies, namely hierarchy-$$ degeneracy [ref] , hierarchy-octant degeneracy, and octant-$$ degeneracy [ref] .
