中微子中性流诱导的单光子产生是包括T2 K在内的基于加速器的中微子束实验中的一个次领先级过程。然而，这是一个需要理解的重要过程，因为它是电子（反）中微子出现振荡实验的背景。在这里，我们进行了这个过程的第一次搜索低于1 GeV的细粒度探测器在T2 K ND 280离轴近探测器。通过由电子-正电子对重构单光子运动学，我们从5.738 × 10^{20}$质子-靶中微子模式数据中获得了95%的纯γ射线样品。我们没有在这个样品中发现中性电流诱导单光子产生的积极证据。我们将该过程的横截面的模型相关上限设置为0.114 × 10^{-38}$cm $^2 $（90\% C.L.）每个核子，使用J-PARC离轴中微子束，平均能量为$\left \sim 0.6$ GeV。这是第一个限制这个过程低于1 GeV，这是很重要的当前和未来的振荡实验寻找电子中微子外观振荡信号。
Neutrino neutral-current induced single photon production is a sub-leading order process for accelerator-based neutrino beam experiments including T2K. It is, however, an important process to understand because it is a background for electron (anti)neutrino appearance oscillation experiments. Here, we performed the first search of this process below 1 GeV using the fine-grained detector at the T2K ND280 off-axis near detector. By reconstructing single photon kinematics from electron-positron pairs, we achieved 95\% pure gamma ray sample from 5.738$\times 10^{20}$ protons-on-targets neutrino mode data. We do not find positive evidence of neutral current induced single photon production in this sample. We set the model-dependent upper limit on the cross-section for this process, at 0.114$\times 10^{-38}$ cm$^2$ (90\% C.L.) per nucleon, using the J-PARC off-axis neutrino beam with an average energy of $\left \sim 0.6$ GeV. This is the first limit on this process below 1 GeV which is important for current and future oscillation experiments looking for electron neutrino appearance oscillation signals.
