核子-核子短程关联

Short-Range Nucleon-Nucleon Correlations

Douglas W. Higinbotham

摘要:

价壳层核子敲除实验,如12 C(e,e 'p)11B,测量的强度比独立粒子壳层模型计算预测的要小。这个问题的理论解决方案是在计算中包括核子之间的相关性。受这些结果的启发,许多电子散射实验试图直接观察这些关联,以获得新的见解核子-核子势的短程部分。不幸的是,许多竞争机制可能导致与初始状态相关性相同的可观察到的最终状态,这使得真正隔离信号极具挑战性。本文回顾了最近关于短程关联的实验证据,并探讨了这种关联对0.3 < xB < 0.7深度非弹性散射比的EMC效应的可能性。

英文摘要:

Valence-shell nucleon knock-out experiments, such as 12C(e,e'p)11B, measure less strength then is predicted by independent particle shell model calculations. The theoretical solution to this problem is to include the correlations between the nucleons in the nucleus in the calculations. Motivated by these results, many electron scattering experiments have tried to directly observe these correlations in order to gain new insight into the short-range part of the nucleon-nucleon potential. Unfortunately, many competing mechanisms can cause the same observable final-state as an initial-state correlation, making truly isolating the signal extremely challenging. This paper reviews the recent experimental evidence for short-range correlations, as well as explores the possibility that such correlations are responsible for the EMC effect in the 0.3 < xB < 0.7 deep inelastic scattering ratios.
