search into high power targetry is needed. Additionally, both the development of a 15 MW proton Anticipated Schedule advances in muon transportation are essential for the success of the MOMENT concept. Central to g measurements is the reduction of systematic errors and accordingly, improved hadron production ection measurements are critical. all participants agreed that the Asian program can be successful and strengthened by the mutual participation.

Since this is a relative measurement, the cross section 1 km 8 km 20 km uncertainty does not come in but the high statistics is important. Once the normalizations of the accelerators are known, then the IBD data can be fit to extract the CP -violating 28 parameter CP . The fit needs to include all the above systematic uncertainties along with the physics parameter uncertainties associated with, for example, the knowledge of sin2 2✓13 and sin2 ✓23 , which are assumed to be known with an error of ±0.005 and ±0.01, respectively.

shown in Figure 2. The neutrino source including the proton driver, target station and pion/muon transport channels can be hosted in the CSNS site [26], and a possible MOMENT detector may be located at the JUNO site. The distance between the two sites is about 150 km, consistent to the average neutrino energy of 200-300 MeV.

Summary • Before 2020, we expect many exciting results. • Between 2020 and 2030, the next (third) generation neutrino experiments will launch for discovery. • We are in the good position to find the new phenomena. Letʼs keep looking for the new with neutrinos. • After 2030, new idea and new technology are welcome to advance neutrino science. • Shall we solve the most of problems that we have today? • Neutrino CP, Majorana neutrino, sterile neutrinos, matter dominant universe, dark matter, dark energy, GUT, etc.. 27
