英文摘要	We study the origin, consequences, and testability of a hypothesis of "partial mu-tau" reflection symmetry. This symmetry predicts vertical bar U mu(i)vertical bar = vertical bar U-tau i vertical bar (i =1, 2, 3) for a single column of the leptonic mixing matrix U. Depending on whether this symmetry holds for the first or second column of U, different correlations between theta(23) and delta(CP) can be obtained. This symmetry can be obtained using discrete flavor symmetries. In particular, all of the subgroups of SU(3) with three-dimensional irreducible representation, which are classified as class C or D, can lead to partial mu-tau reflection symmetry. We show how the predictions of this symmetry compares with the allowed area in the sin(2) theta(23)-delta(CP) plane as obtained from the global analysis of neutrino oscillation data. Furthermore, we study the possibility of testing these symmetries at the proposed DUNE and Hyper-Kamiokande (HK) experiments (T2HK, T2HKK), by incorporating the correlations between theta(23) and dCP that are predicted by the symmetries. We find that when the simulated data of DUNE and HK are fitted with the symmetry predictions, the theta(23)-delta(CP) parameter space gets largely restricted near the charge parity conserving values of delta(CP). Finally, we illustrate the capability of these experiments to distinguish between the two cases leading to partial mu-tau symmetry, namely vertical bar U-mu 1 vertical bar = vertical bar U-tau 1 vertical bar and vertical bar U-mu 2 vertical bar = vertical bar U-tau 2 vertical bar.
