论文摘要
使用广义联系形式主义（GCF）分析了独家$^4 $ he $（e，e'pn）$的短程相关性的测量。我们考虑具有AV18和局部N2LO（1.0）核定核苷（$ nn $）电势的即时形式和轻锥制剂。我们发现运动学分布，例如重建的配对开口角，中子中子动量分布和质量运动的配对中心，以及测得的缺失能量，缺失的质量分布，都通过GCF计算很好地重现。测得的$^4 $ he $（e，e'pn）$ / $^4 $ he $（e，e'p）$横截面比的丢失动量依赖性，对短距离的$ nn $相互作用的性质敏感，也通过互动和配方进行了很好的复制。这使GCF量表分离的分量化描述多体核波功能。
Measurements of short-range correlations in exclusive $^4$He$(e,e'pN)$ reactions are analyzed using the Generalized Contact Formalism (GCF). We consider both instant-form and light-cone formulations with both the AV18 and local N2LO(1.0) nucleon-nucleon ($NN$) potentials. We find that kinematic distributions, such as the reconstructed pair opening angle, recoil neutron momentum distribution, and pair center of mass motion, as well as the measured missing energy, missing mass distributions, are all well reproduced by GCF calculations. The missing momentum dependence of the measured $^4$He$(e,e'pN)$ / $^4$He$(e,e'p)$ cross-section ratios, sensitive to nature of the $NN$ interaction at short-distacnes, are also well reproduced by GCF calculations using either interaction and formulation. This gives credence to the GCF scale-separated factorized description of the short-distance many-body nuclear wave-function.
