论文摘要
我们讨论了在存在非标准相互作用（NSIS）的情况下，在低能量长基线实验（例如T2HK和T2HKK）上振荡概率的分析表达。我们表明，这些实验是探索NSI参数（$ε_d$，$ε_n$）的有利有利的，这些实验被认为是不存在的，以说明太阳中微子和Kamland数据之间的差异。我们还表明，当NSI参数很小时，可以通过组合T2HK和T2HKK实验的数据来解决CP期$δ$，$ε_d$和$ε_d$中的参数退化。
We discuss the analytical expression of the oscillation probabilities at low energy long baseline experiments, such as T2HK and T2HKK in the presence of nonstandard interactions (NSIs). We show that these experiments are advantageous to explore the NSI parameters ($ε_D$, $ε_N$), which were suggested to be nonvanishing to account for the discrepancy between the solar neutrino and KamLAND data. We also show that, when the NSI parameters are small, parameter degeneracy in the CP phase $δ$, $ε_D$ and $ε_N$ can be resolved by combining data of the T2HK and T2HKK experiments.
