Title: 极化$^3$氦靶和SiDIS的末态相互作用

Abstract: Jefferson Lab (JLab) is starting a wide experimental program aimed at studying the neutron's structure, with a great emphasis on the extraction of the parton transverse-momentum distributions (TMDs). To this end, Semi-inclusive deep-inelastic scattering (SiDIS) experiments on polarized $^3$He will be carried out, providing, together with proton and deuteron data, a sound flavor decomposition of the TMDs. Given the expected high statistical accuracy, it is crucial to disentangle nuclear and partonic degrees of freedom to get an accurate theoretical description of both initial and final states. In this contribution, a preliminary study of the Final State Interaction (FSI) in the standard SiDIS, where a pion (or a Kaon) is detected in the final state is presented, in view of constructing a realistic description of the nuclear initial and final states.

Abstract: 杰斐逊实验室（JLab）正在启动一项广泛的实验计划，旨在研究中子结构，特别强调提取部分子横向动量分布（TMDs）。 为此， 将在极化下进行半包容深inelastic散射（SiDIS）实验$^3$He，结合质子和氘核数据，提供TMDs的可靠味分解。 鉴于预期的高统计精度，区分核和部分子自由度以获得初始态和末态的准确理论描述至关重要。 本文贡献呈现了标准SiDIS中末态相互作用（FSI）的初步研究，其中最终态检测到一个π介子（或K介子），旨在构建核初态和末态的实际描述。
