薛定谔模型在闵可夫斯基空间中的Bethe-Salpeter方程解。II。费米束缚态组分

Schrödinger Models for Solutions of the Bethe-Salpeter Equation in Minkowski Space. II. Fermionic Bound-State Constituents

Richard L. Hall, Wolfgang Lucha

摘要:

鉴于在任何试图解决两个费米子的束缚态的闵可夫斯基空间Bethe-Salpeter方程所遇到的障碍,我们研究了建立束缚态特征模型的可能性,至少在定性水平上,由薛定谔描述。这样一个非相对论性的潜力模型可以通过应用,任何给定的贝特-萨尔彼得光谱数据,“几何光谱反演”在其最近的扩展形式,它也容忍奇异的潜力。这导致适应明确的模型,提供了一个概述占贝特-萨尔彼得形式主义的复杂性。

英文摘要:

In view of the obstacles encountered in any attempts to solve the Minkowski-space Bethe-Salpeter equation for bound states of two fermions, we study the possibility to model the bound-state features, at least at a qualitative level, by a Schrödinger description. Such a nonrelativistic potential model can be constructed by applying, to any given Bethe-Salpeter spectral data, "geometric spectral inversion" in its recently extended form, which tolerates also singular potentials. This leads to the adaptation of explicit models that provide an overview accounting for the Bethe-Salpeter formalism's complexities.
