真实μ原子的高分辨率非微扰光阵面模拟

High Resolution Nonperturbative Light-Front Simulations of the True Muonium Atom

Henry Lamm, Richard Lebed

摘要:

通过开发一个名为TMSWIFT的并行程序,对束缚态$(μ^+μ^-)$(真μ素)的非微扰谱进行了广泛的光前量子化研究。使用Padé近似,它已经有可能提取的耦合常数$α$的值的范围内的单重态和三重态的连续和无限截止极限。该数据集允许调查的$α$依赖性的光前光谱,其结果进行比较,以标准计算。还获得了衰变常数。由于第二种较轻的味道($e$)的存在,已经对能量转移进行了改进的计算。最后给出了三味($e$,$μ$,$τ$)计算的初步结果。

英文摘要:

Through the development of a parallel code called TMSWIFT, an extensive light-front quantization study of the nonperturbative spectrum of the bound state $(μ^+μ^-)$, true muonium, has been performed. Using Padé approximants, it has been possible to extract continuum and infinite-cutoff limits for the singlet and triplet states for a range of values of the coupling constant $α$. This data set allows for an investigation of the $α$ dependence of the light-front spectra, the results of which are compared to standard calculations. Decay constants have also been obtained. Improved calculations have been undertaken for the energy shifts due to the presence of a second, lighter flavor ($e$). Finally, initial results for three-flavor ($e$, $μ$, $τ$) calculations are presented.
