Non-Abelian discrete symmetries provide an interesting opportunity to address the flavor puzzle in the lepton sector. However, the number of currently viable models based on such symmetries is rather large. High-precision measurements of the leptonic mixing parameters by future neutrino experiments, including ESSnuSB, T2HK, DUNE, and JUNO, will be crucial to test such models. We show that the complementarity among these experiments offers a powerful tool for narrowing down this broad class of lepton flavor models.

在未来的中微子实验中探索轻子风味模型

非阿贝尔离散对称性为解决轻子领域的风味难题提供了一个有趣的机会。然而，目前基于这种对称性的可行模型数量相当多。未来中微子实验（包括 ESSnuSB、T2HK、DUNE 和 JUNO）对轻子混合参数的高精度测量对于测试此类模型至关重要。我们表明，这些实验之间的互补性为缩小这一广泛的轻子风味模型提供了一个强大的工具。
