人们应该如何表述、提取和解释原子核的“不可观测量”?

How should one formulate, extract, and interpret `non-observables' for nuclei?

R. J. Furnstahl, A. Schwenk

摘要:

原子核的可观测量如结合能和截面可以直接测量。其他物理上有用的量,如光谱因子,通过卷积与测量量相关,卷积的分解不是唯一的。能否为这些原子核结构“不可观测量”系统地制定一个框架,以便从具有已知不确定性的实验中提取这些不可观测量,并用一致性理论进行计算?强子中的部分子分布函数是如何做到这一点的一个说明性例子。还需要一个系统的框架来解决解释问题,例如短程相关性对原子核结构是否重要。

英文摘要:

Nuclear observables such as binding energies and cross sections can be directly measured. Other physically useful quantities, such as spectroscopic factors, are related to measured quantities by a convolution whose decomposition is not unique. Can a framework for these nuclear structure `non-observables' be formulated systematically so that they can be extracted from experiment with known uncertainties and calculated with consistent theory? Parton distribution functions in hadrons serve as an illustrative example of how this can be done. A systematic framework is also needed to address questions of interpretation, such as whether short-range correlations are important for nuclear structure.
