A bstract As it is very promising to expect a discovery of CP violation in the leptonic sector, the precision measurement of the Dirac CP phase δ CP is going to be one of the key interests in the future neutrino oscillation experiments. In this work, we examine the physics reach of the proposed medium baseline muon decay experiment MOMENT. In order to identify potential bottlenecks and opportunities to improve CP precision in MOMENT, we investigate the effect of statistical error, systematic uncertainties, fraction of the muon beam polarity, and adjusting the baseline length to match the first or second oscillation maximum on the precision measurement of δ CP . We also simulate superbeam experiments T2K, NO ν A, T2HK, DUNE and T2HKK in comparison and complementary to MOMENT. To reach the precision of δ CP at 12° or better at 1 σ confidence level, we find it sufficient to combine the data of MOMENT, DUNE and T2HK.
