QED和邻对位电子偶素质量差

QED and ortho-para- positronium mass difference

G. V. Efimov

摘要:

用泛函积分方法研究了相对论QED中的束缚态问题。计算了正、对位正电子的质量差.“非物理”$~$时间变量的贡献被证明是重要的,并导致非解析依赖的束缚态质量的顺序$α^{2\over3}$。结果表明,相对论QED和非相对论QED对这种质量移动给出了不同的结果。此外,出现了所谓的异常状态,如“时间激励”。相对论QED在束缚态问题中的顺序应用与真实的正、对位电子偶素束缚态是矛盾的。结论:相对论QED不适合于正确描述真实的束缚态。

英文摘要:

Bound state problem in the relativistic QED is investigated by the functional integral methods. The ortho- para- positron mass difference is calculated. Contribution of the "nonphysical"$~$ time variable turned out to be important and leads to the nonanalytic dependence of the bound state mass of the order $α^{2\over3}$. It is shown that the relativistic and non-relativistic QED gives different results for this mass shift. In addition so-called abnormal states as "time excitations" arise. Sequential application of relativistic QED to bound state problem is in contradiction with real ortho- and para- positronium bound states. The conclusion: the relativistic QED is not suited to describe real bound states correctly.
