A long range potential the so-called general particle transfer (GPT) potential was proposed for three-body systems almost one decade ago. In this report, we will illustrate another GPT feature from the dispersion theoretical point of view. The index number of the long range potential is related to the exchange particle mass which represents the threshold of multi-pion creation in the potential cut. The index number is proportional to the exchange particle mass. Therefore, the potential with a large exchange particle mass is negligible compared to that with a small mass. Since the quasi-two-body form factors are also given by the GPT potential, then the GPT potential is represented not by a linear form but by an entangled non-linear long range potential. This results in a long range three-body Efimov-type potential.

一系列物理系统中的一般粒子转移势及其远程分量

大约十年前,针对三体系统提出了一种长程势,即所谓的一般粒子转移 (GPT) 势。在本报告中,我们将从色散理论的角度说明另一个 GPT 特征。长程电位的指数与交换粒子质量有关,它代表了电位切割中多π介子产生的阈值。指数与交换粒子质量成正比。因此,与质量小的交换粒子质量相比,交换粒子质量大的势能可以忽略不计。由于准双体形状因子也由 GPT 势给出,因此 GPT 势不是由线性形式表示,而是由纠缠的非线性长程势表示。这导致远程三体 Efimov 型潜力。
