T2 K合作组织报告了一个精确测量μ介子中微子消失的离轴中微子束，峰值能量为0.6 GeV。近探测器测量被用来约束中微子通量和截面参数。位于中微子产生目标下游295公里处的Super-Kamiokande远探测器收集了对应于目标上3.01×10（20）个质子的数据。在没有中微子振荡的情况下，预计将探测到205±17（系统）个事件，而仅观测到58个μ子中微子事件候选者。对中微子速率和能谱的拟合，假设三种中微子口味和正常质量等级，得到最佳拟合混合角sin 2（θ23）=0.514±0.082和质量分裂|Δm（2）|=2.44（-0.15）（+0.17）×10（-3）eV2/c4。我们的结果对应于最大振荡消失概率。
The T2K Collaboration reports a precision measurement of muon neutrino disappearance with an off-axis neutrino beam with a peak energy of 0.6 GeV. Near detector measurements are used to constrain the neutrino flux and cross section parameters. The Super-Kamiokande far detector, which is 295 km downstream of the neutrino production target, collected data corresponding to 3.01×10(20) protons on target. In the absence of neutrino oscillations, 205±17 (syst) events are expected to be detected while only 58 muon neutrino event candidates are observed. A fit to the neutrino rate and energy spectrum, assuming three neutrino flavors and normal mass hierarchy yields a best-fit mixing angle sin2(θ23)=0.514±0.082 and mass splitting |Δm(32)(2)|=2.44(-0.15)(+0.17)×10(-3) eV2/c4. Our result corresponds to the maximal oscillation disappearance probability.
