正电子偶素在O(alpha)和O(alpha^3 ln(alpha))处的闭合寿命

Orthopositronium lifetime at O(alpha) and O(alpha^3 ln(alpha)) in closed form

B. A. Kniehl, A. V. Kotikov, O. L. Veretin

摘要:

最近,对正电子偶素寿命的O(alpha)和O(alpha^3 ln(alpha))辐射修正已经以封闭的分析形式提出,用基本无理数表示,可以用数值计算到任意精度[Phys. Rev. Lett. 101,193401(2008)]。在这里,我们介绍了这种计算的细节,并揭示了这些新常数的性质。我们还列出了重量为4的广义多项式的显式变换公式,这可能是有用的其他应用。

英文摘要:

Recently, the O(alpha) and O(alpha^3 ln(alpha)) radiative corrections to the orthopositronium lifetime have been presented in closed analytical form, in terms of basic irrational numbers that can be evaluated numerically to arbitrary precision [Phys. Rev. Lett. 101, 193401 (2008)]. Here, we present the details of this calculation and reveal the nature of these new constants. We also list explicit transformation formulas for generalized polylogarithms of weight four, which may be useful for other applications.
