有人建议，从太阳中微子和KamLAND实验获得的质量平方差之间的张力可以通过在中微子传播中引入非标准的味道依赖的相互作用来解决。在本文中，我们讨论了在未来的超级神冈实验的大气中微子观测来检验这样一个假设的可能性。假设质量等级是已知的，我们发现太阳中微子和KamLAND数据的最佳拟合值可以在8σ以上进行检验，而全球分析的最佳拟合值可以在5.0σ（1.4σ）处进行检验。
It was suggested that a tension between the mass-squared differences obtained from the solar neutrino and KamLAND experiments can be solved by introducing the non-standard flavor-dependent interaction in neutrino propagation. In this paper we discuss the possibility to test such a hypothesis by atmospheric neutrino observations at the future Hyper-Kamiokande experiment. Assuming that the mass hierarchy is known, we find that the best-fit value from the solar neutrino and KamLAND data can be tested at more than 8σ, while the one from the global analysis can be examined at 5.0σ(1.4σ) for the normal (inverted) mass hierarchy.
