我们研究OPERA实验直接探测ντ的独特能力在多大程度上有助于探测第三族中微子的新的、非标准的接触相互作用。我们对未来的、高度统计的MINOS和OPERA数据进行综合分析。对于νμ到ν转换中的非标准交互作用的情况，我们还包括了可能的双重选择数据的影响。在所有情况下，我们都发现OPERA的ντ样本太小，没有统计意义，即使将OPERA的名义曝光量增加一倍至9×109壶。OPERA对这一测量的真正好处在于它的中微子能量非常高，因此与MINOS相比，L/E非常不同。
We study how much the unique ability of the OPERA experiment to directly detect ντcan help in probing new, non-standard contact interactions of the third family of neutrinos. We perform a combined analysis of future, high-statistics MINOS and OPERA data. For the case of non-standard interactions in νμto νetransitions we also include the impact of possible Double Chooz data. In all cases we find that the ντsample of OPERA is too small to be statistically significant, even if one doubles the nominal exposure of OPERA to 9×1019pot. OPERA's real benefit for this measurement lies in its very high neutrino energy and hence very different L/E compared to MINOS.
