OPERA能帮助限制中微子的非标准相互作用吗?

Can OPERA help in constraining neutrino non-standard interactions?

Andreu Esteban-Pretel, Patrick Huber, Jose W. F. Valle

摘要:

我们研究了OPERA实验直接探测ν τ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。我们对未来的高统计量MINOS和OPERA数据进行了综合分析。对于ν_μ到ν_e跃迁中的非标准相互作用的情况,我们还包括可能的DoubleCHOOZ数据的影响。在所有情况下,我们发现OPERA的ν_τ样本太小而不具有统计学显著性,即使将OPERA的标称暴露加倍到4.5E20 pot。OPERA的真正优势在于它的中微子能量非常高,因此与MINOS相比,L/E非常不同。

英文摘要:

We study how much the unique ability of the OPERA experiment to directly detect ν_τcan 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 ν_μto ν_e transitions we also include the impact of possible DoubleCHOOZ data. In all cases we find that the ν_τsample of OPERA is too small to be statistically significant, even if one doubles the nominal exposure of OPERA to 4.5E20 pot. OPERA's real benefit for this measurement lies in its very high neutrino energy and hence very different L/E compared to MINOS.
