摘要:

本文给出了在$E_ν\le 1 GeV$能区的一些核靶的(反)中微子感生CCQE截面的结果。该研究的目的是面对电子和μ子生产相关的$ν_μ\leftrightarrow ν_e$或$\barν_μ\leftrightarrow \barν_e$振荡实验的截面。讨论了轻子质量及其运动学意义、第二类流以及轴向和赝标形状因子的不确定性对自由核子和束缚在核中的核子的(反)中微子诱导反应截面的影响,其中核介质效应影响截面.计算采用了考虑核子关联效应的局域费米气体模型。详情见参考文献。[1]的文件。

英文摘要:

We present the results of (anti)neutrino induced CCQE cross sections from some nuclear targets in the energy region of $E_ν\le 1 GeV$. The aim of the study is to confront electron and muon production cross sections relevant for $ν_μ\leftrightarrow ν_e$ or $\barν_μ\leftrightarrow \barν_e$ oscillation experiments. The effects due to lepton mass and its kinematic implications, second class currents and uncertainties in the axial and pseudoscalar form factors are discussed for (anti)neutrino induced reaction cross sections on free nucleon as well as the nucleons bound in a nucleus where nuclear medium effects influence the cross section. The calculations have been performed using local Fermi gas model with nucleon correlation effects. The details are given in Ref.[1].
