Exploring Partial μ – τ Reflection Symmetry in DUNE and Hyper-Kamiokande

In this work, we study the consequences of the ‘partial μ – τ ’ reflection symmetry and the testability of the corresponding symmetry predictions at the upcoming experiments: Deep Underground Neutrino Experiment (DUNE) and Hyper-Kamiokande (HK) experiment. Each prediction |Uμi|=|Uτi|(i=1,2,3) when applied to a single column of the leptonic mixing matrix U gives rise to different correlations between θ<inf>23</inf> and δ<inf>CP</inf>. We tested the correlations from the two leading cases of partial μ – τ reflection symmetry, namely | U<inf>μ</inf> <inf>1</inf>| = | U<inf>τ</inf> <inf>1</inf>| and | U<inf>μ</inf> <inf>2</inf>| = | U<inf>τ</inf> <inf>2</inf>| using the experiments, and also examined the sensitivity of these experiments to distinguish between the two cases.
