摘要:

我们定量地研究了CCQE和CCRes相互作用中假事件的百分比以及末态相互作用对沙丘中微子振荡参数的影响。共振相互作用将是DUNE振荡敏感区的主要相互作用。在一个理想的和现实的探测器的情况下,DUNE振荡物理的末态相互作用的效果进行了分析。利用LAr探测器研究了$ν_μ$消失振荡信道。我们发现,核效应和探测器的阈值起着重要的作用,在CCQE和CCRes的相互作用,这些核效应诱导一个显着的偏差,在确定大气振荡参数。在这项工作中,对测定$θ_{23}$的核效应的印象进行了量化。

英文摘要:

We quantitatively study the percentage of fake events present in CCQE and CCRes interactions and the impact of final state interactions on the neutrino oscillation parameters at Dune. Resonance interaction will be the most dominant interaction in the oscillation sensitive region of DUNE. The effect of final-state interactions for DUNE oscillation physics is analysed in an ideal and realistic detector scenario. The $ν_μ$-disappearance Oscillation channel is studied using LAr detector. We find that nuclear effects and detector thresholds plays an significant role in CCQE and CCRes interactions and these nuclear effects induces a significant bias in the determination of atmospheric oscillation parameters. The impression of nuclear effects on the determination of $θ_{23}$ is quantified in this work.
