The structure of positronium is governed almost completely by QED; strong and weak corrections are small compared to electrodynamic effects. This makes it an ideal laboratory for studying QED and the bound state formalism in quantum field theory. The objective of the research is to study the energy levels and decay rates in positronium. The emphasis will be on the calculation of order alpha2 corrections to these energy levels and decay rates and to complete the evaluation of the n=1 and n=2 positronium energy levels through order m*alpha2. Completion of these calculations will provide an important test of the bound state formalism and QED.

正电子素的结构几乎完全由量子电动力学控制；与电动力学效应相比，强校正和弱校正很小。 这使其成为研究 QED 和量子场论中束缚态形式主义的理想实验室。 该研究的目的是研究正电子素的能级和衰变率。 重点是计算这些能级和衰变率的α2阶修正，并通过m*α2阶完成n=1和n=2正电子素能级的评估。 这些计算的完成将为束缚态形式主义和量子电动力学提供重要的检验。
