In this research, neutrino interaction with water target has been studied with water Chereckov detector by using accelerator produced neutrino beam in the K2K experiment, which is the first long baseline neutrino oscillation experiments in the world. We constructed the 1 kt water Cherenkov detector at High Energy Accelerator Research Organization (KEK) as a near detector of the K2K experiment. We have observed many neutrino interactions with the 1 kt water Cherenkov detector since 1999. The expected number of interactions at Super-Kamiokande is estimated by using the 1 kt water Cherenkov data to be 80.6+7.3-8.0, while 56 events were observed. The 1 kt water Cherenkov data has been also used to study various kind of neutrino interactions, such as neutral current interactions, possible fake events of proton decay events. Those results will be published soon.

在这项研究中，已经通过在K2K实验中使用加速器产生的中微子束来研究与水靶的中微子相互作用，这是世界上第一个长的基线中微子振荡实验。我们在高能量加速器研究组织（KEK）上构建了1 kt水切伦科夫检测器，作为K2K实验的近检测器。我们已经观察到自1999年以来与1 KT水Cherenkov检测器的许多中微子相互作用。通过使用1 KT Water Cherenkov的数据为80.6+7.3-8.0，可以估计超级Kamiokande的预期相互作用数量，而观察到56个事件。 1 KT水Cherenkov数据也已用于研究各种中微子相互作用，例如中性电流相互作用，质子衰减事件的假货事件。这些结果将很快发布。
