论文摘要
能量弹药张量（EMT）的耐达形式因素对最近的文献引起了极大的兴趣。这尤其涉及D期形式D（t），其在内部力量方面具有吸引力。迄今为止，他们的重点是强子结构，理论研究集中在具有短距离力的强烈相互作用的系统上。尚未研究由于远距离相互作用（例如电磁相互作用）对EMT的影响。电磁力在质子内部力的平衡中起着很小的作用，但是它们的远距离性质引入了新功能，这些特征在具有短距离力的系统中不存在。我们使用质子的简单但一致的经典字段理论模型来展示远程力的存在如何改变一些在短距离系统中授予的概念。我们的结果表明，在存在远程力时需要更仔细的D-期限。
The hadronic form factors of the energy-momentum tensor (EMT) have attracted considerable interest in recent literature. This concerns especially the D-term form factor D(t) with its appealing interpretation in terms of internal forces. With their focus on hadron structure, theoretical studies so far have concentrated on strongly interacting systems with short-range forces. Effects on the EMT due to long-range forces like the electromagnetic interaction have not yet been studied. Electromagnetic forces play a small role in the balance of forces inside the proton, but their long-range nature introduces new features which are not present in systems with short-range forces. We use a simple but consistent classical field theoretical model of the proton to show how the presence of long-range forces alters some notions taken for granted in short-range systems. Our results imply that a more careful definition of the D-term is required when long-range forces are present.
