Exclusive Studies of Short Range Correlations in Nuclei and the EMC effect using CLAS12

近程相关核子-核子（NN）对约占中重核所有核子的20%，约占核动能的75%。此外，有强有力的证据表明这些对与原子核中的核子结构修饰（电磁兼容效应）有关。SRC研究中有许多悬而未决的问题，只能通过对选定细胞核的高统计研究来解决。这些研究包括三核子SRC的存在和性质、约束神经网络相互作用和近距离核波函数的从头计算、理解分解有效理论和有效SRC的形成机制、研究三核子相关性以及探索SRC与EMC效应的详细联系。该项目将通过分析在class12中使用核目标获得的关键反应来解决这些悬而未决的问题。

Short-ranged correlated (SRC) nucleon-nucleon (NN) pairs account for about 20% of all nucleons in medium to heavy nuclei and about 75% of the nuclear kinetic energy. In addition, there is strong evidence linking these pairs to nucleon structure modification in nuclei (the EMC effect). There are many open questions in SRC studies that can only be addressed via high-statistics studies of selected nuclei. These include the existance and properties of Three-Nucleon SRCs, constraining the NN interaction and ab-initio calculations of the nuclear wave function at short distances, understanding factorized effective theories and effective SRC formation mechanisms, studies of three-nucleon correlations, and exploring the detailed connection of SRCs and the EMC effect. The project will focus on addressing some of these open questions by analysing key reactions obtained using nuclear targets in CLAS12.
