T2 K报告了它的第一个测量参数的消失，在离轴束由于中微子振荡引起的味道变化。在J-PARC产生的峰值能量为0.6GeV的准单色束，在295公里外的远探测器Super-Kamiokande上观测到，预计那里的存活概率是最小的。利用靶上质子对应的数据集，观察到34个完全包含的类事件。最佳拟合振荡参数分别为和，置信区间分别为和，为68%。这些结果与现有的反中微子参数测量结果以及T2 K测量的消失参数一致。
T2K reports its first measurements of the parameters governing the disappearance ofin an off-axis beam due to flavor change induced by neutrino oscillations. The quasimonochromaticbeam, produced with a peak energy of 0.6 GeV at J-PARC, is observed at the far detector Super-Kamiokande, 295 km away, where thesurvival probability is expected to be minimal. Using a data set corresponding toprotons on target, 34 fully contained-like events were observed. The best-fit oscillation parameters areandwith 68% confidence intervals ofand, respectively. These results are in agreement with existing antineutrino parameter measurements and also with thedisappearance parameters measured by T2K.
