摘要:

我们报告的研究结果,旨在量化的影响的振荡分析的不确定性与描述的中微子-核截面在两个粒子-两个孔部门。我们的计算结果,基于能量重建的运动学方法,并进行了比较两个数据驱动的方法,表明中微子截面中存在的差异有相当大的影响提取的振荡参数,特别是在反中微子通道。

英文摘要:

We report the results of a study aimed at quantifying the impact on the oscillation analysis of the uncertainties associated with the description of the neutrino-nucleus cross section in the two-particle--two-hole sector. The results of our calculations, based on the kinematic method of energy reconstruction and carried out comparing two data-driven approaches, show that the existing discrepancies in the neutrino cross sections have a sizable effect on the extracted oscillation parameters, particularly in the antineutrino channel.
