我们使用完整的MINOS数据样本报告v(e)和(v) over bar (e)在v（mu）和(v) over bar （mu）光束中的外观。将735公里基线上的这些v(e)和(v) over bar (e)外观数据与反应堆实验测量的theta（13）进行比较，探测delta、theta（23）八阶简并度和质量层次。该分析是该技术的第一次使用，并包括第一次加速器长基线搜索(v) / bar (mu) -> (v) / bar (e)。我们的数据不支持31%（5%）由delta、theta（23）的八次方和68% (90%)C.L.的质量层次所定义的三参数空间。我们测量的值为2sin(2)(2 theta(13))sin(2)(theta(23))，这与反应器实验一致。DOI: 10.1103 / PhysRevLett.110.171801
We report on v(e) and (v) over bar (e) appearance in v(mu) and (v) over bar (mu) beams using the full MINOS data sample. The comparison of these v(e) and (v) over bar (e) appearance data at a 735 km baseline with theta(13) measurements by reactor experiments probes delta, the theta(23) octant degeneracy, and the mass hierarchy. This analysis is the first use of this technique and includes the first accelerator long-baseline search for (v) over bar (mu) -> (v) over bar (e). Our data disfavor 31% (5%) of the three-parameter space defined by delta, the octant of the theta(23), and the mass hierarchy at the 68% (90%) C.L. We measure a value of 2sin(2)(2 theta(13))sin(2)(theta(23)) that is consistent with reactor experiments. DOI: 10.1103/PhysRevLett.110.171801
