论文摘要
与孩子（韩国-IBS-DAEGU-SKKU）核能密度功能相关的孩子，研究了带电的中微子核散射。我们专注于由轴向质量和中等内部有效质量造成的不确定性。将理论的结果与MiniBoone，T2K和Miner $ν$ A的最新数据进行比较，我们限制了与数据兼容的轴向质量和有效质量。我们发现总横截面对有效质量不敏感，因此可以独立于有效质量的不确定性确定轴向质量。另一方面，不同运动学处的差分截面对有效质量和轴向质量敏感。在总横截面的轴向质量的不确定性中，检查了对有效质量的依赖性。结果，我们获得了与实验数据一致的轴向质量和有效质量。
Charged-current neutrino-nucleus scattering is studied in the quasielastic region with the KIDS (Korea-IBS-Daegu-SKKU) nuclear energy density functional. We focus on the uncertainties stemming from the axial mass and the in-medium effective mass of the nucleon. Comparing the result of theory to the state-of-the-art data from MiniBooNE, T2K, and MINER$ν$A, we constrain the axial mass and the effective mass that are compatible with the data. We find that the total cross section is insensitive to the effective mass, so the axial mass could be determined independently of the uncertainty in the effective mass. Differential cross sections at different kinematics are, on the other hand, sensitive to the effective mass as well as the axial mass. Within the uncertainty of the axial mass constrained from the total cross section, dependence on the effective mass is examined. As a result we obtain the axial mass and the effective mass that are consistent with the experimental data.
