论文摘要
分析了用于电动电流的准层和中性弹性中微子散射的通量集成的半活化差异截面。横截面是使用相对论扭曲的波脉冲近似值计算的，其值是核子轴向质量$ m_a = 1 $ GEV和1.2 GEV的值。还计算出弹性散射横截面，以针对中性轴向外形的不同奇怪的夸克贡献。对于SBN实验的远探测器，评估了通量积分的差分横截面作为重建的中微子能量的功能。短基线中微子振荡的影响在3+1框架中考虑到。我们发现，横截面取决于振荡参数，并且可以在无菌中微子振荡研究中使用测量和预测的横截面的比率。
Flux-integrated semiexclusive differential cross sections for charged-current quasielastic and neutral-current elastic neutrino scattering on argon are analyzed. The cross sections are calculated using the relativistic distorted-wave impulse approximation with values of the nucleon axial mass $M_A=1$ GeV and 1.2 GeV. The elastic scattering cross sections are also computed for different strange quark contributions to the neutral-current axial form factor. The flux-integrated differential cross sections as functions of reconstructed neutrino energy are evaluated for the far detector of the SBN experiment. The effects of the short base-line neutrino oscillations are taken into account in a 3+1 framework. We found that cross sections depend on oscillation parameters and the ratio of the measured and predicted cross sections can be used in a sterile neutrino oscillation study.
