非阿贝尔规范理论中的三圈计算

Three-loop calculations in non-Abelian gauge theories

O. V. Tarasov, A. A. Vladimirov

摘要:

详细描述了三圈对重整化群函数贡献的解析计算方法。用这种方法计算了费米子非阿贝尔规范理论在三圈近似下的电荷重整化函数和反常维数。给出了QCD有效电荷的三圈表达式。SU(4)-超对称规范模型中的电荷重整化效应在这个能级上消失。附录中给出了所需公式的完整列表。上述三回路计算的结果已由本作者(与A. Yu.,Zharkov和L. V.,1980年,在Physics Letters B.本书对这一问题作了更详细的论述,并包含了许多计算技巧,也于1980年作为JINR通信E2-80-483出版。

英文摘要:

A detailed description of the method for analytical evaluation of the three-loop contributions to renormalization group functions is presented. This method is employed to calculate the charge renormalization function and anomalous dimensions for non-Abelian gauge theories with fermions in the three-loop approximation. A three-loop expression for the effective charge of QCD is given. Charge renormalization effects in the SU(4)-supersymmetric gauge model is shown to vanish at this level. A complete list of required formulas is given in Appendix. The above-mentioned results of three-loop calculations have been published by the present authors (with A.Yu., Zharkov and L.V., Avdeev) in 1980 in Physics Letters B. The present text, which treats the subject in more details and contains a lot of calculational techniques, has also been published in 1980 as the JINR Communication E2-80-483.
