摘要

2016年，在J-PARC中微子束线上，将装有65kg铁靶的乳化液云室(ECC)暴露在中微子束下。它能够探测低至200mev /c的慢质子。在本文中，我们使用的数据集对应于0.40$\乘以$10$^{20}$质子在目标上。共成功重建了194个中微子-铁带电电流相互作用。测量了每个事件末态中介子和质子的发射角和动量，并与蒙特卡罗模拟结果进行了比较。这是首次在该能量区域使用铁ECC进行测量。

First cross section measurement of neutrino charged current interactions in the iron ECC

Emulsion Cloud Chamber(ECC) with 65kg iron target was exposed to the neutrino beam at J-PARC neutrino beamline in 2016. It is capable of detecting slow protons as low as 200 MeV/c. In this document, we use the data set corresponding to 0.40$\times$10$^{20}$ protons on target. A total of 194 neutrino-iron charged current interactions were successfully reconstructed. Emission angles and momenta of muon and protons in the final state of each event were measured and compared with those of a Monte Carlo simulation. This is the first measurement using the iron ECC in this energy region.
