T2 K首次测量了中微子能量下碳上的带电电流相互作用，测量结果被报告为μ子动量和角度的通量平均双微分截面。用束流Monte Carlo方法和包括NA 61/SHINE实验结果在内的外部数据对通量进行了预测。用于测量的数据是在2010年和2011年获得的，共有个质子在目标上。在近探测器的最上游细粒闪烁体探测器中选择的4485个带电电流相互作用候选者上进行分析。在平均中微子能量为0.85GeV时，通量平均的总截面为<$σCC <$σ =（6.91±0.13（stat）±0.84（syst））×10-39 cm ~ 2核子。
T2K has performed the first measurement ofinclusive charged current interactions on carbon at neutrino energies ofwhere the measurement is reported as a flux-averaged double differential cross section in muon momentum and angle. The flux is predicted by the beam Monte Carlo and external data, including the results from the NA61/SHINE experiment. The data used for this measurement were taken in 2010 and 2011, with a total ofprotons-on-target. The analysis is performed on 4485 inclusive charged current interaction candidates selected in the most upstream fine-grained scintillator detector of the near detector. The flux-averaged total cross section is ⟨σCC⟩ϕ=(6.91±0.13(stat)±0.84(syst))×10-39 cm2nucleon for a mean neutrino energy of 0.85 GeV.
