中微子诱发反应中的核效应

Nuclear effects in neutrino induced reactions

摘要:

本文讨论了核介质效应在当前感兴趣的一些中低能中微子反应分析中的相关性。特别是,我们研究了准弹性(QE)过程,RPA相关性和最终状态相互作用(FSI)被证明发挥了至关重要的作用。我们还研究了中微子诱导的相干π介子产生。我们发现由于π波函数的扭曲和核中产生机制的修改,截面有很大的减小。还研究了结果对轴向$NΔ$耦合$C_5^A(0)$的灵敏度。

英文摘要:

We discuss the relevance of nuclear medium effects in the analysis of some low and medium energy neutrino reactions of current interest. In particular, we study the Quasi-Elastic (QE) process, where RPA correlations and Final State Interactions (FSI) are shown to play a crucial role. We have also investigated the neutrino induced coherent pion production. We find a strong reduction of the cross section due to the distortion of the pion wave function and the modification of the production mechanisms in the nucleus. The sensitivity of the results to the axial $NΔ$ coupling $C_5^A(0)$ has been also investigated.
