论文摘要
使用外部字段方法，{\ it i.e。\/}评估有效的动作$ v _ {\ mathrm {eff}} $对于任意强的常数和均匀的字段，我们探索了Qed的非驱动性属性，允许任意的gyromagnetic比率$ g $ $ g $。我们在$ g = 2 $ in：a）QED $ B_0 $ - 肾上腺化组系数以及b）b）中包含伪cudoscalar $ {\ cal p}^{2n} =（\ cal p}^{2n} =（\ vec e \ cdot \ cdot \ cdec b）^cos cusp的Qed $ b_0 $ - 肾上飞机限制的QUSP cusp。 $ b_0 $的属性暗示着亚伯理论中$ g $渐近自由的某些域。
Using the external field method, {\it i.e.\/} evaluating the effective action $V_{\mathrm{eff}}$ for an arbitrarily strong constant and homogeneous field, we explore nonperturbative properties of QED allowing arbitrary gyromagnetic ratio $g$. We find a cusp at $g = 2$ in: a) The QED $b_0$-renormalization group coefficient, and in the infinite wavelength limit in b) a subclass containing the pseudoscalar ${\cal P}^{2n}= (\vec E\cdot\vec B)^{2n} $ of light-light scattering coefficients. Properties of $b_0$ imply for certain domains of $g$ asymptotic freedom in an Abelian theory.
