Measuring CP violation by low-energy medium-baseline neutrino oscillation experiments

In this talk, we discuss the possibility of measuring CP violation in neutrino oscillation experiments using the neutrino beam with energy which is lower Eν≳100 MeV than the one usually considered (typically >1 GeV) in accelerator experiments. The advantage of using such lower energy neutrino beam is that despite the smaller detection cross-sections, the effect of CP violation is larger and the optimal length of the baseline can be rather short, 30–50 km, being free from matter effect contamination.
