论文摘要
至少三个长度尺度对于获得核物理学的完全了解很重要。这些是细胞核的半径，平均核子间分离距离和细胞核的大小。通过使用示例证明短途和高动量转移物理之间的直接连接以及波浪功能的高动量含量是不可避免的，可以检查不同量表之间的连接。核大小是通过独立对近似与核子核子分离距离连接的，并且该距离通过虚拟概念与EMC效应连接。后者的解释是根据QCD的光较前全息波函数提出的。最终结果是三个量表密切相关，因此，对任何给定特定量表范围的狭窄关注可能会阻止对核性质的基本起源的理解。还确定，在某些适当的条件下，实验能够测量波函数的动量依赖性。
At least three length scales are important in gaining a complete understanding of the physics of nuclei. These are the radius of the nucleus, the average inter-nucleon separation distance, and the size of the nucleon. The connections between the different scales are examined by using examples that demonstrate the direct connection between short-distance and high momentum transfer physics and also that significant high momentum content of wave functions is inevitable. The nuclear size is connected via the independent-pair approximation to the nucleon-nucleon separation distance, and this distance is connected via the concept of virtuality to the EMC effect. An explanation of the latter is presented in terms of light-front holographic wave functions of QCD. The net result is that the three scales are closely related, so that a narrow focus on any given specific range of scales may prevent an understanding of the fundamental origins of nuclear properties. It is also determined that, under certain suitable conditions, experiments are able to measure the momentum dependence of wave functions.
