超越非相对论极限的μ介子谱
Muonium spectrum beyond the nonrelativistic limit
摘要:
本文将盖尔曼-洛定理推广到反介子-电子系统。用数值方法提取了束缚态谱。结果,精细和超精细结构在非相对论极限附近(和任意质量)被正确地再现。我们比较光谱的相对论值α = 0.3与相应的计算在光前量子化。
英文摘要:
A generalization of the Gell-Mann-Low theorem is applied to the antimuon-electron system. The bound state spectrum is extracted numerically. As a result, fine and hyperfine structure are reproduced correctly near the nonrelativistic limit (and for arbitrary masses). We compare the spectrum for the relativistic value alpha = 0.3 with corresponding calculations in light-front quantization.
