The leptonic CP phase has profound physical consequences due to its possible connection with leptogenesis for explaining the existence of matter in the Universe. To some extent, the leptonic CP phase is even more important than the Higgs boson that provide mass for all fundamental particles. If we cannot understand the existence of matter, why we need to care about their mass. However, the current accelerator experiments for CP phase measurement suffer from new physics such as non-unitarity mixing (NUM) and (vector, scalar, dark) non-standard interactions (NSI). It is necessary to find extra experimental configuration to guarantee CP sensitivity at T2(H)K, NOvA, DUNE, and T2HKK.
